So, my office's holiday party is this week & I need to bring a White Elephant gift. I've never participated in one of these gift exchanges before, so I'm not really sure what it's supposed to be. People kinda make it sound like it should be kind of a gag gift? I really hate gag gifts. Trying to buy a shitty present on purpose is making my skin crawl. Someone please just tell me what to buy so I can worry about something else. ($20 max limit)
