The Gremlin

This guy walks into a pub with a gremlin sitting on his shoulder. He sits at the bar and orders a pint and a half of lager.

The gremlin downs his half-pint, runs long the bar, dips his head in a blokes beer and goes:

- Brrr!

The guy orders another pint and a half. The gremlin repeats the performance. The bloke grabs the gremlin by the neck, shakes him up a bit, and says:

- Listen, if you ever do that again I'll cut yer balls off!

The gremlin says:

- Ain't got none!

- Well, I'll cut off yer prick!

- Ain't got one of them, neither. - says the gremlin.

- Well, how do ya pee?

The gremlin smiled and said:

- Brrr!
