Bones -- "The Dwarf in the Dirt"
First Stewie Griffin from Family Guy stopped by Bones... now Homer Simpson! Ok, just Dan Castellaneta, the voice behind the Simpsons patriarch. Any Simpsons fan worth their salt would recognize the actor (and if you're playing Fox's Simpsons Scavenger Hunt, that's a big blinding clue). Castellaneta plays a fellow law enforcement officer who just happens to find a green skeleton at the bottom of a sinkhole.
What do you get when you put a little green man, gold coins and a rainbow together? That's right kids! A leprechaun... or, in this case, a midget wrestler who's persona is a leprechaun and who broke into a gold exchange to nab enough money to win the heart of his "normal" size twin brother's wife. Yeah, we know. It's a head spinner. Ah, what some men wouldn't do when blinded by love.
Speaking of: Booth's still off his game. He's practicing to re-qualify as a sharpshooter and it's not going well. The former sniper for the Army Rangers is barely hitting the target. Desperate, Booth turns to Dr. Gordon Wyatt (that's CHEF Wyatt now, thank you very much), for advice. He suggests that all the little things such as forgetting his "cocky" belt buckle or which hand he uses to hold a cell phone are not symptoms of the brain surgery, but manifestations of his angst in loving Brennan. Chef Gordon advises Booth to give her some time to come around on her own (Noooo! You're killing us!). In the meantime, bring her to the range when takes the qualification test, he can't miss.
Booth: "I just need you to help me aim my gun."
Chef Gordon Gordon Wyatt: "That sounds desperately phallic. Is it a... sexual problem?"
