For me it had to be when my 60 year old mother channeled her inner diva in Rock Band and belted out the vocals to a bunch of songs. Of course by "belting out" I mean "timidly muttered", but to her credit she sang several songs--of her own volition--without even knowing the words. At one point I looked around and realized I was playing a video game with my sister, girlfriend, and mom. It was surreal, hilarious, and great fun.

I should have formed a band right then and there: Kato's Angels.

Did you have any amusing holiday moments with friends, family, pets, or loved ones?
