Fat-arsed colonel

The phone rang at the motor pool and an authoritative voice demanded to
know how many vehicles were operational. Paddy answered, "We've got
twelve trucks, ten utilities, three staff cars and that Bentley the
fat-arsed colonel swanks around in."

There was a stoney silence for a second or two.

"Do you know who you are speaking to?"

"No," said Paddy.

"It is the so-called fat-arsed colonel you so insubordinately referred
to."

"Well, do you know who you are talking to?"

"No," roared the colonel.

"Well thank Christ for that," said Paddy slamming the phone down.
