Ringer Fan Diana writes that the Simpson's spoofed Gollum on last evening's episode in the USA. She was unsure if it was really Andy Serkis voicing the character, but wrote: He played a cowboy who gathered up the remains of a picnic at a Dude Ranch being visited by the Simpsons, scooping up all the trash into a sack, whispering 'My preciousssssssss' ... N3M0 adds that as the credits rolled, Andy's name did come up, so looks like it really was Andy on the Simpsons.
