Most of my favourite quotes have already been mentioned, so i'll just pick something else:
"This is a pet trainers nightmare. You try and get it to behave, and all it does is puke snot on you and moan" (ep. 15 just after he gets out of the drainage pipe and says "I am a gopher!", that was hilarious too)
Btw, I am new to the forum, so: Hi Ross Scott! Hi everyone!
