20! Crunches

We're all guessing how many repetitions of various exercises Goosey will be doing.

Goosey: Okay, how many crunches?

Randy: LOL

Randy: 15!

Goosey: Any other guesses? Give me a number to shoot for! :D

Sentynel: 20!

Sentynel: That's an excited 20, by the way. Not 20 factorial.

Goosey: LOL

Goosey: THANK YOU

Goosey: Hehehe.

Sentynel: 2.43290201 × 10^18 crunches might take you a while.
