"Dumb Luck" was better than "No Body Loves Grim" in my opinion because I felt the things that happened to Billy werent as bad.
Anyway, "Dumb Luck" had us seeing character development in Mandy. She shows concern for Billy, which she will in "Which Came First?". Anyway, I did feel awkward with Billy's bad luck and I hated the snail. He was so ugly and diabolical. Anyway, I liked Grim's puns. They are much better than those of Numbuh 2 (Codename: Kids Next Door). So overall, the episode was alright, except for the part wehn Billy was naked. I could have sworn I saw his crotch! The little circular thing could have also been a badly drawn belly button.
Ok, lets not get drawn away! "No Body Loves Grim" was a pun-intended title but maybe it was a little too cruel. I mean, I already feel sorry for the poor guy. The episode was alright with Grim's body but the ending made me not care much for this episode. So, overall, i think the episode could have done much better than it actually did.
