Two UNC students

Two UNC students named Trish and Tina were walking down the street. 

Trish noticed a compact on the sidewalk and leaned down to pick it up.

She opened it, looked in the mirror, and said, "Hmmm, this person looks familiar."

Tina said, "Let me look!" So Trish handed her the compact.

Tina looked in the mirror then turned to Trish. "You silly... that's *me*!
