A man walks into a sperm bank wearing a mask and pointing a gun.
He goes up to a nurse and demands that she open the sperm bank vault.
She says "But sir, it’s just a sperm bank!", "I don't care, open it now!" he replies.
So she opens the door to the vault and inside are all the sperm samples.
The man says "Take one of those sperm samples and drink it!”.
She looks at him "BUT, they are sperm samples!", "DO IT!" he shouts.
So the nurse sucks one back.
"That one there, drink that one as well.", so the nurse drinks that one as well.
Finally after 4 samples the man takes off his mask and says….
"See honey - it’s not that hard."
