Script Who S On First

How to Script Who's On First for Performance or Production

The Abbott and Costello routine "Who's on First" is one of the most referenced comedy pieces in performance history, but getting it right on paper or on stage requires more than memorizing a script. The structure depends entirely on misdirection through naming conventions, and the rhythm breaks if you don't understand where each beat lands. Here is how to actually handle it. The core mechanism is straightforward once you map it. One person (the straight man) introduces players whose first and last names are literally positions on a baseball team. The second person (the comedian) asks who is on each base, and the confusion comes from the fact that "Who" is the player's first name, "What" is the player's last name, and "I Don't Know" is the shortstop. You can find a complete script by searching for the original 1938 radio version or the 1945 film recording, both of which are widely available online. The full cast list of name-position pairs runs like this:

First base: Who / What
Second base: Why
Third base: Because
Shortstop: I Don't Know
Catcher: Because
Left field: Who
Center field: What
Right field: I Don't Know This creates the primary loop. The straight man says the name, the comedian insists they are asking about the position, and the straight man keeps confirming the same thing from a completely different angle. The pattern repeats until it collapses into nonsense. That collapse is where the comedy lives, not in the setup. I ran into a specific problem when adapting this for a classroom production a few years back. The script calls for a rapid-fire exchange, but performers tend to slow down at each "Who" to let the audience laugh, which kills the momentum. By the third rotation, the rhythm is so broken that the later lines land flat. The workaround was to mark the script with tempo instructions directly in the margins. I wrote "speed up" after every successful misunderstanding and "hold for laugh" only on the rare moments where the comedian repeats a phrase the straight man has already confirmed twice. That cut the performance time from about four minutes to roughly two minutes and twenty seconds, and the audience response was noticeably better because the confusion accumulated faster than it could be resolved.

Common Pitfalls in Scripting and Performance

Most people mess this up by not committing to the literal reading. The straight man must treat every name as completely normal. If there is even a hint that he finds the situation strange, the illusion fails. The comedian, meanwhile, has to genuinely believe the straight man is being unhelpful rather than just stating facts. This asymmetry is what creates the comedic tension. When both players are equally confused, there is nothing to laugh at. Another issue is the ending. The routine traditionally resolves when the straight man says "I Don't Know" in response to a question about the third baseman, and the comedian replies that the shortstop is I Don't Know, then third is Because, and the whole thing folds. Some versions add an extra layer where the catcher is also Because, which adds about thirty seconds but can feel repetitive. I recommend trimming the catcher line unless you have a partner who can sell the additional frustration. The most useful resource for anyone working with this script is the actual Abbott and Costello recording from the film Buck Privates. Listening to it at least twice before attempting a performance will show you the timing better than any written guide. The original performance is approximately two minutes and forty seconds long. Transcribed versions online often add unnecessary stage directions that clutter the dialogue. A clean transcript with just the spoken lines is usually the most practical format for rehearsal.
