This pic goes around every Thanksgiving. It is not photoshopped. You can do this yourself. Impress your prevy friends, embarrass your children, and piss off those conservative relatives to the point they will never come back. Talk about making for a Happy Thanksgiving.
To do this at home, cut two lemons of about the same size in half. Then slide the halves with the 'nipple' on the end, under the skin of the turkey.
I have done this on a chicken, it worked great. Gave a nice lemony flavor to the breast meat.
