I'm sorry I didn't know it was her turn."

There was a husband and his wife sitting next to a drunk in a
bar. Suddenly the drunk stands up and yells, "ATTENTION
ALL" and farts loudly.

The wife is extremely embarrassed, and the husband looks at
the drunk and says" Excuse me, you just farted before my
wife."

The drunks replies," I'm sorry I didn't know it was her turn."
