Paddy and Murphy come across a girl whose bike has a flat tire...
Murphy leaves Paddy to help her and goes on his way.
A few hours later, Paddy passes Murphy on the girl's bike.
"What the fek happened"? asks Murphy.
"Well, I fixed her bike and be jaysus she takes her 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 fekin knickers wouldn't fit ya anyway"
