Wow, this thread is HOPPIN'!

It's a nasty thing to say, but I LOVE it when he either gets angry or scared. His reactions to the Cannibal Ghost thing in 'Blooooooo' (especially that 'Hum-a-na hum-a-na hum-a-na') basically had me fits of laughter. The ways he just explodes like in 'Where There's a Wilt there's a Way' and 'Bus the two of us' is even better. When ever I watch 'Bus the two of us' on my DVR I just sit there for a least (or until my Mum comes in and tells me that she's not watching THIS rubbish and I need to turn it off) an hour watching him shouting down the phone over and over again. I find it quite hilairious.
