Search Results: cheesy pick up lines

OK, this guy asked me out on Valentine's day and used cheesy pick up lines like "Do you have a band-aid because I hurt my knee when I feel for you?". Then he introduced me to his friends, which helped him in making me think he was serious. (I thought he was joking, like that prank in high school where a guy pretends to like a girl). After a month, he told his friend that I was his girlfriend when we weren't even dating and told him "She digs me". During tennis practice, he used the "go make me a sandwich" joke. He asked me to prom on one knee (like he was proposing to me but it was probably because of my small height). The girls team tease me about him saying he doesn't do this to any other girl but he's waiting for the right one and our coach would be like "(his name), control your woman" or "(my name), I hear you have his picture on your bedroom wall". He teases me a lot too. Everyone says that he is serious but I wasn't sure if they were part of the joke. My sister and his sister said that he was joking. And no, his sister does not hold a grudge against me. so, what do you think? Is he serious? Please state why or why not.
