So there are two blokes, one quite tall and his mate, a dwarf, gone on a long weekend to Hamburg.
They hit the town on the pull.
Anyway, half way through the evening - no luck, so they decide to go their own ways in a bid for success.
They both return to their hotel about the same time and the tall bloke spots the dwarf with a 6'2" well built woman on his arm.
The tall bloke, alone, goes into his room and lies on the bed, frustrated.
After a short while he can hear, coming from the dwarfs' room "A one, two, three urrgh". And again, "A one, two, three, urrgh".
This carries on for a couple of hours and the tall bloke falls asleep.
The next morning, at breakfast, the tall bloke says to his mate the dwarf, "it sounded like you had a good time with that lady last night".
"Good time?" he says. "Good time?"
"I couldn't get on the bleeding bed!"
