If they think you are C&F then you are already attactive to them. If you are just a clown then you are a "Funny Guy" and they see you as nothing more. You need to get some Kino going, make your interactions more sexual. Stand closer, get some touching going on, tease them, and call them on their BS when they dish it out.
If you are sure the girls whos numbers you have will know it is you, then just text them and say.
You: "I thought about you today!"
HB: "What did you think" (99% reply)**
You: "I saw a bunch of Ooompa Loompas, crossing the street and thought Short People are breeding way too much!"
**Her: "Who is this?" (1% reply)
You: "You are (her name), the question is who am I?"
Simple as that.
Peace...
