You are on a crowded bus when you suddenly realize you need to fart.
The music is really loud, so you time your farts with the beat.
You let go about 5 strong and loud ones back to back.
After a couple of songs, you start to feel better as you approach your stop.
As you are leaving the bus, people are really staring you down, and
that's when you remember; you've been listening to your iPod!
