I tend to not like them but once in a while I do...but they do tend to wreck a song circle if you ask me...once they start they don't stop...one person had a great idea..it was verboten to sing a parody of a song after the original had been sung, tempting though it may be. well, people like them...in somehting like a music camp it is a good idea to have parody workshops and that seems to give them an outlet... mg
