A pervert was wandering around and saw a beautiful female clerk in a pharmacy, so he decided to go and flirt with her.
The pervert (pretending to be shy): Excuse me, do you sell condoms here?
Female clerk: Yes, we do.
The pervert: But it's my first time using one, I don't know how. Can you give me a demonstration?
The female clerk (glanced at him curiously) and said indifferently: If you take yours out, I'll give you a demonstration.
