There is no shortage of these internet challenges flying around the internet but I think we might have found the best one to date. I give you the UnderBoob Challenge. Its pretty simple, a female gets a pen, pencil, marker, or whatever else is laying around and then they try and use only thier boob to hold it. So they lift the boob up and slide the pen into the underboob and see how long they can hold it I guess.
You got to admit, it damn sure is more entertaining then the Ice Bucket Challenge
