SECOND DEGREE
Two blondes are walking down the street. One notices a compact on
the sidewalk and leans down to pick it up. She opens it, looks
in the mirror and says, 'Hmm, this person looks familiar.' The second blonde says, 'Here, let me see!' So the first blonde hands her the compact.
The second one looks in the mirror and says, 'You dummy, it's me!'

(Do keep a lookout of the rest of the degree in later post)
