Had to pass gas

I was in the restaurant yesterday when I suddenly realized I desperately 
needed to pass gas. The music was really, really loud, so I timed my 
gas with the beat of the music. 

After a couple of songs, I started to feel better. I finished my coffee, 
and noticed that everybody was staring at me.... 

Then I suddenly remembered that I was listening to my iPod.

Backwards

Some people's noses and feet are built backwards: their feet smell and their noses run.
