For school:
you: Would you like to come over and study math after school today?
her: sure im really worried about the text Friday.
you: i was thinking we could start with a little review of flash cards then we can add the bed, subtract the clothes, divide the legs and multiply.
anywhere else:
you: so i saw the weirdest thing the other day.
her: yeah, like what?
you: so i saw this girl and she had a bunny here (touch your hand to her closest shoulder) and another one here (reach your arm around her and place it on her other shoulder). <apply a confused smile> and i forgot the rest of the story but it probably wasn't as interesting as you anyways.
Around easter:
i say around easter because this one requires a prop. around easter, in most drug stores, you can find these small "stuffed" chicks (baby chickens). in addition to the stuffing they have a speaker inside that when the brass brads on bottom are both touching your hand causes the chick to make a small but noticeable chirping sound.
set up: casually locate your self near an attractive girl. with the chick in your pocket so to speak.....lol puns. begin making the chirping sound. appear oblivious to the noise until she notices it.
girl: (notice this is the first one where she begins the conversation) do you hear that noise?
you: what do you mean?
girl: that squeaking noise, you don't hear it?
you: oh you must mean this. <show here the chick> a friend gave me this on easter, he said it was a "chick call", i had no idea what he was talking about but it seems to work better than i would ever have expected.
the last one was a personal invention after my x-girlfriends mom gave me said prop in an easter basket - its the one thing from that relationship that i still have.
