A couple was planning on getting married. Seeing how they didn't have much money to go on a honeymoon, they decided tojust go back to their new apartment after the wedding.
The groom had three close friends, that were prone to committing practical jokes. One being a carpenter, the other a ordinary guy, and the third a dentist.
They all decided to pull practical jokes on their newly married friends. The carpenter decided he would cut the slats in the bed so that when they climbed into bed, the bed would collapse. The ordinary guy decided to short sheet the bed, so that when they got into it their feet wouldn't reach the bottom. The dentist chuckled and wouldn't tell anyone what he planned to do.
A week later the 3 friends all received letters in the mail. "Dear friends, we didn't mind the fact that when we got into bed, the bed collapsed, or the guy that short sheeted it, but I'm gonna kill the bastard that put the novacaine in the vaseline!"
