This happened in Feb 22/11 in an afternoon class.

Me: Can I be in your team?

Luke: Sure.

(I found out we were the only team of 2 and the others were made of 4)

Luke: We'll be a one-man team.

Teacher: What's your team name?

Luke: Team I don't care.

Teacher: Pick a color.

Luke: Uh... purple?

Me: (Hey purple is my favorite color!)

So that's how Team Purple became to be.
