Two sharks are swimming in the sea... One shark sees a school of sardines, and says ""bro you hungry?"" and the other shark says ""nah, I'm good. You go for it."" So the first shark swims right into the sardines, and nom-nom-noms on hundreds of the little fishes. Minutes later, the shark curls up in pain. ""Oooh, aaaagh, uuuurgh...."" the second shark says ""What's the matter?"" and the first shark says ""I forgot you're supposed to wait half an hour before swimming after you eat... >_<""
