Needs wholesome family-fun prank to bond with your kids this year? Look no further than Whamageddon! The game is pretty simple, just try to avoiding hearing the song "Last Christmas" by popular '80s duo Wham! until Christmas Eve and you win! (Here's an entire site with more thorough instructions.) It's a game of survival. And you can't just go up to your opponent and press play off of your phone and shove the song into their ear. You have to get way more creative than that. For example, after this mom got "whammed" by her daughter this year, she sneakily went into her daughter's phone, and changed all of her downloaded songs to actually be the infamous "Last Christmas." So when she goes in to listen to what she thinks is Taylor Swift or something, WHAM!, tricked ya, it's actually "Last Christmas." It seems to be a roaring great time for the families who participate in Whamageddon and they have no shame in coming up with ways to send their parents or children to "Whamhalla." If you and your family choose to play this year, we wish you luck!
