A guy walks into a sperm donor banking wearing a ski mask and holding a gun.He goes up to the nurse and demanded her to open the sperm bank vault.
She says " But sir, its just a sperm bank".
"I don't care, open it now!!!" he replies.
So she opens the door to the vault and inside are the sperm samples.
The guy says "Take one of the sperm sample and drink it!".
She looks at him astonished . "But they are sperm samples??".
" Do it!".
So the nurse sucks it back.
"That one there,that one and that one as well". So the nurse drinks all four samples.
Finally after the four samples has been consumed by the nurse the man takes off his ski mask and say
" See honey -its not that hard after all".
