Me: John, what did he do earlier?
John: Hold on, I’m trying to think.
Me: I thought I smelled poop.
Listen up, chucklehead. So, the guy asks John what someone did, right? John's thinking hard, but the first guy interrupts and says he smells poop. Get it? The 'poop' smell is supposed to be John's 'thinking'. You probably thought it was a legit fart joke, didn't you?
