Input: Text: teenage boys are stupid. it's a fact of life that will never change. my friends and i especially prove this to be true. earlier today while my friend was showering i decided to pull a harmless prank. i wanted to confuse and annoy my showering friend by dropping a something onto him. looking around for potential weapons i narrowed it down to shaving cream and a bottle of honey. because i didn't want to get my fingers sticky i chose the shaving cream. then i walked into the bathroom and put my hand above the shower curtain and sprayed down the target. but there were a few things i had not considered. not being able to see my friend, i had assumed he would not see the shaving cream canister aimed at him and that he would definitely not look directly at the nozzle. i also neglected to think of any possible repercussions if the shaving cream got into his eyes. by his screams of pain i could tell shaving cream in the eyes is a lot worse than soap. after 5-10 minutes of persistent burning i decided to man up and get parents involved. fearing the worst i told his mom what happened. she simply called me an idiot, gave me a disapproving look and helped her son rinse out his eyes. at one point i was sure he would end up in the er. but eventually the pain faded and the swelling went down but he still had a serious case of stink-eye directed at me.
