#3. My Face Condoms ($32 for 25)
If you show these to your buddies, you're a hilarious goofball who knows how to have a good time. If you show these to a woman, you're a potential serial killer. You've been warned.
#4. Finger Condoms ($17 for 24 @ Amazon.com)
These are fantastic for 1) guys who are hung like ants, and 2) guys with awful hand-washing hygiene.
