Fundies

 On the greatest TV Show ever, Arrested Development, character Tobias Funke increased awareness of Gymnophobia - a fear of being naked. As a never-nude, he always wore a pair of jean shorts underneath his clothing, and it had a negative effect on his love life. But thanks to the invention of the Fundie, those with Gymnophobia can still engage in the most human of acts.

The Fundie is underwear built for two, and while it is ridiculous, there's a certain amount of logic to its basic design. Plus, you can't get pregnant if you're both wearing underpants, right?
