Flirting As A Physicist

The physics pickup lines are strong with this one. From quantum states ("I'm down"/"I'm up") to the observer effect ("behave differently when you're observing"), this conversation hits all the quantum mechanics sweet spots. The "infinitely large potential barrier" reference is particularly nerdy - that's quantum tunneling humor for you. In classical physics, particles can't cross energy barriers higher than their own energy, but quantum mechanics says "hold my beer" and lets particles tunnel through anyway. Romance at the subatomic level is complicated, yet somehow still follows Heisenberg's uncertainty principle - the more precisely you measure the attraction, the less certain you are about where the relationship is going.
