One is always loath to explain a joke. In face-to-face badinage, the joker can judge the comprehension of the jokes from their immediate reactions. Failing to win the approving smiles, chuckles, or belly laughs, the raconteur has a choice of remedies including the Quick Exit Strategy ("What a dumb crowd. I’m out of here!"). The modest teller will accept the blame ("Oh, I forgot to mention that the mother-in-law was a blond Republican Fortran programmer!") and order drinks all around. It’s the bore unwilling to accept defeat who embarks on a detailed analysis heralded by an aggressive, "You don’t get it, do you?"
