just run into him accidently and say hey ive been looking for you wanna go out or hey will you go out with me or make up a good excuse like you need help on a class project but a class that hes in can you help me maybe we can go out and help each other on our projects or writing assignments homework etc or you could say hey i really would like to get to know you more you seem really cool wanna go out sometime
Um try walking up to him, grabbing him by the ears and saying your taking me out tonite or else your ears come off bucko. That would impress him and everyone else around you, he would be to scared to say no.
Okay, if you want a creative way to ask him out (i've done this before and it turned out great) is get a few paople to randomly give him blocks of butter throught the day. Then have the office call him down and there waiting for him is a thing of popcorn with a note that says "Now that I've buttered you up, will you go out with me?" It's a lot of fun and then I put my name at the bottom of the bowl so he had to eat the popcorn before he found out who it was from. That way you don't have to get up the nerve and face him yourself :)
