A Blonde girl and an Irish guy are in a bar when all of a sudden the Blonde girl notices something strange about the wellington boots that the Irish guy' is wearing on his feet .

She says to him: "Excuse me mate, Im not being funny or nothin, But why does one of your wellies have an L written on it, and the other one's got an R written on it?"
So, the Irish guy smiles, puts down his pint of Guinness on the bar and replies: "Well, oy am a little bit tick you see. This one with the R is for me roight foot and this one with the L is for me left foot."

"Cor, yeh !" exclaims the Blonde girl, "So that is why my knickers 'have got C&A printed on the label."
