Heard this one, many years ago.

Pilot's phone rings, and he picks it up without thinking.

"Hello?"

"Capt Effemcee? This is the Crew Desk, and we have a trip for you."

"Umm.......just a minute."

Covering the phone loosely with his hand in a deliberate bid to falsely mute it, he says:

"Honey, it's for your husband!"
