Wrong names

Things have been more than a little rocky lately, but there are still plenty of fun/funny moments.

I have a student that I'll call Teddy here.  We have a hot and cold relationship; he has been known to tell me off, but he also brought me a homemade Valentine's Day cupcake with a teeny paper heart that said "What the formula for happy V-Day" (sic).

T raises his hand for help.
Ms. P: Yes, Theodore?
T: That's not my name.
Ms. P:  No?  Teddy is your full name?
T: Yes.
Ms. P:  Oh.  Too bad, I kinda feel like calling you Theodore anyway.
T (shooting me a mock dirty look): Fine.  Ms. G.
Ms. P (laughing heartily): You have no idea how funny that actually is.

Ms. G is the other physics teacher, and last year when we were both brand new white female physics teachers, everyone, including the principal, secretary, school police, and 2/3 of the teaching staff, called both of us Ms. G.  All year.  Nobody called her Ms. Pippi, but I got called Ms. G on a daily basis (her name is much more common and easier to remember, spell, pronounce than my real name).
