This episode was fun to watch because it was so surprising.
Mandy, who clearly has no intrest it boys is infatuated with Billy's new friend. She then proceeds to ask Grim to rip her heart out but Grim has other ideas. When Grim falls for a goth chick, they use many movie references to add some humor. However they may have gone a little too far with the "When Harry Met Sally" joke. Sure, it probably went right ove most kids heads, but still. Talking about "doing it" no matter what "it" is, just doesn't belong in a cartoon aimed at kids. All in all though this episode was very enjoyable.
