3 Irish monks1 have passed all tests, except for one. It is the test of purity. So the other monks tie bells to their dicks and put them in a room with a naked chick. She dances in front of the first one, and, sure enough, he goes 'ding-ding!'

Go take a cold shower, now! she commands, and he goes to take a shower. So she dances in front of the next one, and, after a couple of minutes, he goes 'ding-ding!'

Go take a cold shower with your brother! she yells, and he leaves. Now she goes to the last one, dancing in front of him. He doesnt ring. The woman nods.

Good, you've passed. Go take a shower with your brothers.

Ding-ding!
