Thanksgiving is a few days away and we have a lot to be thankful for. With the holiday comes classic Thanksgiving episodes from several shows. Some of my favorite ones included the "Friends" episode when Monica put the turkey on her head and the Thanksgiving love triangle on "90210." Or in "How I Met Your Mother" when Marshall got to slap Barney in the Slapsgiving episode. Take a look down memory lane after the jump. Which Thanksgiving shows are your favorite?
