A woman gets onto a bus with her baby.
The bus driver says, “That’s the ugliest baby that I’ve ever seen. Ugh!”
The woman goes to the rear of the bus and sits down, fuming. She says to a man next to her, “The driver just insulted me!”
The man says, “There’s no call for that. You go right up there and tell him off.
Go ahead; I’ll hold your monkey for you.”
"In riposte to any double meaning naughty suggestion, "I beg your pardon" should be used. "I beg your pudding" is the jocular form." J.P. Donleavy from The Unexpurgated Code A Complete Manual of Survival & Manners
