Blair, Jo, Natalie, Tootie, Molly- each has been in a serious situation and each was punished- but a good spanking added to the punishment would certainly have been appropriate!
Blair and Jo for sneaking into a club
Molly for pretending to be sick (OK, so she deserves only a quick spanking for this one)
Tootie for getting drunk. Blair and Jo again for buying the alcohol, underage.
Natalie was probably the best behaved, but was along with her friends, and so got punished too. So any spanking the others got, she should share partly too.
Actually, it could kind of have been like being at a BU party
