Can't remember the worst gift, but best gift was my Audi TT from the girlfriend... I mean, now wife... :-)
Worst gift would have to be from my step uncle who is gay. He thought it was just too darn funny when I unwrapped a butt plug. Did not help that my grand mother was right there, and had no idea what it was. No joke.
Best gifts would have to be the Ruger 22 Bearcat, and Win model 94 30-30 my grandma gave me ages ago.
