"Do You Have Any Threes?"

Weldon: Have any threes?

Greg: Go fish

Weldon: I drew a three, I get to guess again! Do you have any threes?

Greg: WHAT ARE YOU TALKING ABOUT?

Weldon: I have two threes now, and I drew the guess, I get to ask again!
Do you have any threes?

Greg: Ummm, yes.

Weldon: I now have three threes! Do you gave any threes?

Greg: I'll give you my three.

Weldon: I have made a book of threes! I get to guess again! Do you have
any threes?

Greg: NO, I don't have any threes, if you had 3, and I gave you one, then
you have all four! How could I have any more threes? How many decks are
you playing with?

Weldon: I am not playing with a full deck! Do you have any threes?

Go fish!
