Headache
A man was complaining to his coworker about a terrible headache he was experiencing. The coworker said, When I have a bad headache, I just lay my head on my girlfriends bosom for a while, and it goes away. You really should try it.
The next day, the man with the headache said to his coworker, You know, your advice about how to get rid of my headache was great! After work last night, I did just exactly what you said, and my headache disappeared after just a little while! Oh, by the way, your girlfriend has a really nice apartment!
