the wherewithall (spelling)

Poet: So, I would like to make a deal with you. I mean, instead of just asking
you for money, I will ask you for a word. Yeah, You give me a word, I take the
word, and then, and then I will write a poem, with the word inside. And if you
like it, I mean, if you like my poem, and you feel it adds something to your
life in any way, then you can pay me whatever you feel like. I will write in
English, of course.
Selene: Okay.
Jesse: Great, alright.
Poet: So? Pick a word.
[Jesse and Selene look at each other]
Jesse: Ummm...
Selene: A word, uh... milkshake.
