A guy with a balaclava walks into a bank

(Dutch joke, hope this translates well)

So a guy with a balaclava on his head walks into a bank screaming: "This is a robbery!!"

The woman behind the counter responds: "B-but sir, this is no ordinary bank, this is a sperm bank"

"I don't give a shit! I want a litre of sperm and I want it now"

"S-Sorry? A litre of sperm?

"A Litre of sperm or I'll shoot you"

So the lady goes and gets a litre of sperm for the for the robber.She comes back with a bottle and the robber yells: "Drink it!"

"S-sorry?

"Drink it, or I'll shoot you!"

So the lady drinks the whole bottle.

The robber then pulls of his balaclava: "See Mary, I told you, you could hold it in!!"
