What is a good move to play on him so that he cant say no?

i like this boy his name is neeko . and he is totally cute and hes mixed. i always say hi to him when he gets on the bus in the morning . i need a good way to ask him out but not making my self look desperate while keeping him from saying no. EXAMPLE: i was watching prom the new movie and the dude put 2 rocks in front of her house saying yes or no to prom ,but the yes was on a pebble and no was on a huge bolder . i want something like that but simple something a teenager can actually do without having to give up a limb!-----(in my range of ability's)
