In a lab meeting... "I knew taking you on was a mistake, what with your history of mental problems....you won't pass, I only took you because of the reputation of your undergraduate supervisors..."
(mental problems actually means depression...and c'mon, who doesn't get depressed when doing a PhD??!!)
And then when she was drunk at a Christmas dinner...."You are the most inspirational young female scientist and you remind me of myself at your age, except I was better".
And on my first day..."I'm sorry, who are you?"
And then a few moments later..."Oh yes, I had forgotten. You have braces. My mother was an oral surgeon. Open your mouth so I can see". (and i did, my mouth was open anyway at the fact she didn't know who I was!!!!).
