A girl goes to a date with a Jewish guy
They sit on a hill at night, looking at the stars. The guy seems very shy, and so they sit in silence.
Wanting to break the awkward silence, the girl says "A penny for your thoughts", the guy smiles and replies "Well... will you hug me?", she gets closer and he puts his arm around her.
A few minutes pass and once again, they sit in silence. The tries again: "A penny for your thoughts" the guy blushes and says "Well... will you kiss me?", the girl giggles and they kiss.
A good half-hour passes and once again, they sit in silence. The girl desperetly wants the date to end well, so she says "A penny for your thoughts". The guy turns red and says "Well... this time my thought are way more serious...". Excited, they girl says "Tell me!"
The guy opens his hand and says: "Isn't it about time you give me those two pennies from earlier?"
