They're Labeled for a Reason

At work I have ear buds for my iPod.  They are labeled with an "L" and "R" to indicate the appropriate ear to stick them in.  Today, I accidentally picked up the "R" ear bud and stuck it in my left ear.  I thought I was going to have a heart attack.  I was totally grossed out.  Cross-ear-waxation is not something I take lightly.
