    Apparently, there is a somewhat common prank where once person will tap his or her beer on top of yours, causing yours to explode into a foamy mess.

    Apparently, the physics behind this were interesting enough for actual scientists to dedicate time and money to figuring out why it happens.

    Who would have thought it was so complicated.

    Premature bubblication caused by extreme arousal from the inadvertent (or not so inadvertent) touching by a member of the opposite (or same for 10% of y'all out there) beer style.
