Funnily enough, I LOVED Jeanine Garofalo on this show. I'm one of the few. However, her character always struck me as 'they wanted to get Mandy back and couldn't' and I think I'd read speculation to that effect somewhere. I'm also one of the few who likes Mandy.

michelle_k, by the way, was infamous for being one of the Amy/Donna shippers. For two opposing interests, they don't share nearly enough scenes together. A regret.
