USA Today put together this list of the most germ-infested parts of an airplane . . . you know, just to make your air travel experience somehow LESS pleasant than it already is.

#1.)  The bathroom.  There are germs on basically every surface, usually including E. coli.  The bathrooms don't get a full sanitizing between most flights, and the small sink makes it hard for people to properly wash their hands.

#2.)  The tap water.  Make sure to ONLY drink bottled water on the plane.  Studies have shown that airplane water filtration techniques still aren't perfect, so you run the risk of drinking some Mexico-quality water.

#3.)  The free pillows and blankets.  Sometimes the airlines will have time to change the pillowcases.  But sometimes they won't.

And since about 5% of airline passengers tend to be sick, there IS a chance you'll get a pillow that just got drooled on by a sick person.

#4.)  The SkyMall catalog.  Yes, even the beloved SkyMall catalog is trying to kill you, while it sells you useless lawn ornaments and iPod docks shaped like '50s diner jukeboxes.  People touch the catalog with their germ-filled hands all the time.
