The Abbott and Costello Routine Everyone Tries to Quote But Nobody Gets Right

I've seen people try to perform the Who's On First bit at parties for years. Most of them butcher it because they memorize lines without understanding the structural mechanism underneath. The sketch isn't funny because of random nonsense dialogue. It works through phonological ambiguity layered over a rigid call-and-response format. Once you see the machinery, you can appreciate why it's held up for ninety years while every other vaudeville routine from the same era vanished. When I first tried to transcribe it for a linguistics class back in the early 2000s, I hit a wall pretty fast. The routine exists in multiple versions — the 1945 film routine, the earlier radio broadcasts, the stage versions. They're not identical. The 1945 Bud Abbott and Lou Costello film version is what most people reference, but if you're looking for the Transcript Of Who S On First for academic or performance purposes, you need to know which recording you're actually working from. I learned that the hard way after I spent three hours trying to reconcile two versions that had different line orders in the second act.

Why the Confusion Works Structurally

The core technique is homophonic confusion. Every character name on the team (First, Second, Third, What, Who, I Don't Know) is also a functional word in English conversation. Abbott uses the names as labels. Costello interprets them as interrogative pronouns, questions, or negations. This creates a collision between referential language and conversational language. Here's the part most analyses miss: the routine only functions because Abbott stays completely straight. He never breaks character, never clarifies, never acknowledges that Costello is misunderstanding him. Abbott treats every name as a proper noun throughout. Costello treats them as common nouns or question words. The humor emerges from the friction between those two interpretations. It's not improvisation. It's scripted to the word.

Getting the Transcript Right

If you need an accurate transcript, the best source is the 1945 film Because I'm Still Crazy About You, which preserved the full routine. The radio versions from the 1938-1946 period are also useful for comparison. YouTube has full performances, but be careful — a lot of uploaders add captions that are wrong because they're guessing at the dialogue rather than working from a reliable source. I ran into this when I was compiling references for a presentation. Someone had uploaded a version where "Who's on first?" was transcribed as "Who's your first?" in the captions. It's subtle but it completely breaks the script if you're trying to study it. For the exact text, I recommend checking published collections like The Complete Abbott and Costello or the scripts archived by the University of Wisconsin's Institute for Research in the Humanities. Those go through verified sources rather than crowd-sourced captions. A complete transcript runs roughly two pages single-spaced depending on formatting.

Common Mistakes People Make

The biggest error is treating it as improv. It's not. Every beat is timed. If you skip or rearrange sections, the rhythm collapses. The routine has a specific escalation pattern — Costello starts confused, gets angrier, Abbott remains flat, and it ends with Costello hitting his head against the locker. That ending matters structurally. It's the physical release after ninety seconds of purely verbal frustration. Cutting it changes the piece. Another mistake is paraphrasing. People will say "something like this" and then rewrite parts in their own words. Don't. The specific wording is the whole point. Lines like "The guy on third base — What's his name?" are designed to force the listener through the same mental loop that Costello experiences. Rewriting it destroys the mechanism.

Where It Falls Apart

Being honest about limitations: the routine is impossible to perform well without a partner who understands the timing. Watching someone practice it alone reveals how dependent it is on Abbott's deadpan delivery. If the straight man laughs even once, the whole thing unravels. I've seen groups try this at corporate events and the transcripts didn't help because nobody actually understood the call-and-response rhythm. The words on the page look straightforward. Performing them requires exactly calibrated miscommunication. Also worth noting: the routine relies on mid-twentieth-century American sports context. Some of the humor assumes you understand baseball positions and the concept of a batting lineup. The non-baseball sections still work, but the third-inning structure gives the whole thing its backbone. Audiences outside that cultural frame sometimes miss the setup entirely. If you're studying it academically, the Routledge Handbook of Comedy or entries in The Encyclopedia of Humor Studies have decent analyses of the linguistic structure. For performance, find a good video reference and work with someone who can play Abbott while you do Costello. The transcript alone won't get you there.
