Can Someone Tell Me?

What is with BOYS and STAR WARS!?!? I don't get it!!!! I got 3 Star Wars valentines in my bag. One has Mannequin Skywalker, another has that green dude, Coda (is he a little seasick?), and one with the girl that has cinnamon rolls on her ears. And one of those was handwritten and said "May the force be with you!____"!!! I DON'T GET IT! Can someone with a son, brother, I don't care who it is, tell me PLEASE! Another example:

Today we (the girls) were banging our hands on the table singing "Dadada! Dadada! ELMO'S WORLD!" and the boys made it "Dadada! Dadada! STAR WARS!"


PLEASE.
