The Hairdresser scene...
Normally I would think Mercedes was an attractive and sexy women, but she looks like an absolute homely dog next to Michelle Pfeiffer. When Michelle was getting her her done and sitting in that barber's chair she just cast such a gorgeous stare that I was almost bemused by her beauty in that moment.
When Mercedes gets all annoyed with her friends and scowls that Pfeiffer is such a stuck up bitch, you can believe why women would so easily be offended by her.
