Well, if you're really up for it. You could always move them the GSC and delete the moves there. --- http://img694.imageshack.us/img694/7705/1261460599031.gif http://img268.imageshack.us/img268/9027/259v.gif
Sticky topic has this information, but I'll explain here.
GSC (or G/S/C) simply refers to the Pokemon Gold, Silver & Crystal games.
In this case, there's a Move deleter in Blackthorne City, and Pokemon Stadium 2 also has a "Move Relearner" (reward for beating the Elite 4) that can all erase HM moves. --- Where logic won't work - I will Assdammit you theening bud. You'll pasy for this. - NAU_Trackrunner
The move relearner can only teach a pokemon level-up moves, so if you've wiped over any TMs in the past, they're gone. --- Where logic won't work - I will Assdammit you theening bud. You'll pasy for this. - NAU_Trackrunner
