Paddy and Murphy come across a woman whose bike has a flat tyre...
Murphy leaves Paddy to help her, and goes on his way.
A few minutes later, Paddy passes Murphy on the woman's bike.
"What the feck happened"? asks Murphy.
"Well, I fixed her bike and be jaysus she takes her fe*kin knickers off, lies on the ground and says, 'take what you want big boy!", so I took the bike.''
"Good on ye'' says Murphy, ''I'm sure the fe*king knickers wouldn't fit ya anyway"
