The best way I know to wish you a Happy Thanksgiving is to share some laughter with you. Laughter of course from perverted yet humorous Thanksgiving pick-up lines. Enjoy your dinner and hopefully a lil' something sweet for dessert :)
"Your spread looks amazing. I can't wait to dive in!"
The Hostess will definitely appreciate that you appreciate all her hard work!
"Wanna pull my wishbone? Go on, make a wish and give that sucker a tug."
"There's only one cavity I wanna stuff if you know what I'm saying." (However, a raw carcass is pretty nasty considering salmonella can be a deal breaker!)
