So i was riding this type of skateboard thing called a ripstick (http://www.ripstikusa.com/) with my friend smidge. He was walking i was riding then i hit this big ass hole in the ground.  I didn't fall but i stumbled.  These kids in a school bus all start yelling at me things like "Hey dumbass don't fall.  Retard learn how to walk. etc"  So i sat down my friend smidge looks at me and goes "dude are you crying". I look at him with tears in my eyes laughing like crazy and he goes whats so funny.  I look at him and say "they are calling me a dumbass, but they are in fucking summer school"    Lesson learned: If u are trying to call someone stupid, dont ride in a bus that says summer school on the side.
