One of my favorite episodes was the one in which Homer grew hair. That was a very unique episode, since there was a gay secretary, but that wasn't even the issue of the show-the issue was Homer's image changing because he had hair.
“Nothing's sacred anymore. Those girls and I got so close. They were painting me naked every day for months. It was kind of like going to a really bizarre sleepover. It's what you guys imagine we do: One naked girl and seven pairs of hands all over her.”
