"Open the fucking safe" he yells at the girl behind the counter.

"But we're not a real bank" she replies, "we don't have any money, this is a sperm bank".

"Don't argue, open the fucking safe or I'll blow your head off" She obliges and once she's opened the safe door the guy says.

"Take out one of the bottles and drink it".

"But it's full of sperm!" she replies nervously.

"Don't argue, just drink it" he says.

She prises the cap off and gulps it down.

"Take out another one and drink it too" he demands.

She takes out another and drinks it as well. Suddenly the guy pulls off the balaclava and to the girl's amazement it's her husband.

"There," he says "it's not that fucking difficult is it!"
