Paddy and Murphy are sitting in the pub.
Paddy: I'm just off over there to chat the woman up.
Murphy: Ok.
Paddy: Hello there, you're looking sexy tonight.
Woman: Actually I'm a lesbian.
Paddy: What's a lesbian.
Woman: Well you see that woman over there with the big boobs and the short skirt? I'd like to take her to bed and lick her minge out.
Paddy: I asked her and she said she's a lesbian.
Murphy: What's a lesbian?
Paddy: I'm still not quite sure, but I think that I'm a lesbian as well.
