The Garage Door
Boss walks into his office one morning unaware his flies were open.
His secretary noticed this and being very discreet, went into his office and asked if he'd closed his garage door, then left.
He was puzzled by this, and later on went to the toilet were he noticed his flies were undone.
He came out of the toilet and went over to to his secretary and asked her if she'd noticed a big Humvee through the open door, . . she replied she had'nt, . . but said she'd seen a mini with two flat tyres.
