A response to a story told by someone else that is used to show that it might have been funny, but the way they tell it it doesn't sound funny at all.
Georges: "...and he was like "wait, we don't sell that here, nevermind!" HAHAHAHAHAHAHAHAHA"
Geoff:(doesn't laugh) "Hmm, guess you had to be there."
