Sign Language...

[snags]

Johnny takes his girlfriend home to meet his parents but warns her that they're both deaf and dumb.

They get there and walk into the living room. Mum has a beer bottle up her fanjita and Dad has his nuts hanging out and a match stick propping one eye open.

His girlfriend says, "what the fcuk is this?".

Johnny replies: "oh, it's sign language. Mum is saying "Get the beers in ya cnut" and Dad is saying "B0ll0cks, I'm watching the match!''
