The question is what more than DEREK will he bring?
Well!! We've seen all of Derek's faces by now, i think...
Eugene is so nice.. but the rest keep annoying him (ie about bins)...
Won't it be interesting to see him crack???
Without Derek, how will he cope?? The annoying lot might get to him so much that he'll crack, scream at them all and get really anrgy!!!
I for one am looking forward to such a possibility.
C'mon!

he's great!! They don't show all his funniest moments... but cmon, who heard the Rainbow impression???
