A woman is in bed with her lover - her husband's best friend. During sex the phone rings.
Because it's the woman's house, she reaches over and picks up the receiver.
The guy listens in only hearing her side of the conversation.
She is speaking in a cheery voice. "Hello? Oh, Hi! So glad you called. Really?... That's wonderful! I'm so happy for you. Sounds terrific. Great! Thanks! Okay. Bye-bye."
She hangs up the phone and the guy asks, "Who was that?
"My husband, telling me what a wonderful time he's having on his fishing trip with you."
