There were three young priests about to take their final vows. The last test that they had to pass was the celibacy test. For this, all three had to strip naked and tie a little bell around their penis. After this, a belly dancer entered the room and started slinking around the first priest...
The chief priest said "Oh, Patrick, I'm disappointed. You've failed. Go and have a shower."
The belly dancer had stripped as far as her last veil for the second guy before the chief priest heard...
"Ting a ling"
"Joseph, I'm very disappointed. You can't resist the temptation of a woman. Go for a shower."
The belly dancer started dancing totally naked now around the last priest. She did everything erotic she could think of... but no bell rang!
"John, I'm delighted. You've passed! You can resist the temptation of women. Now, go relax and take a shower with Patrick and Joseph"
