How do I talk to this incredibly handsome guy i don't know!!

I've seen this incredibly handsome guy at school and he is all I think about know...But I don't have any classes with him ( because he is a upperclassman ... sadly) , and I only see him at breakfast and I try to sit sorta close to him but I just want to meet him because it looks like he has a girl or something.. but how do I introduce myself without look desperate, just so I can at least know him a little? NOT to be mean but Please don't tell me to just say hey because that's weird and nobody does that in high school , espicially if you don't know that person..
