This guy who calls himself the LA Beast has a bunch of videos of him on the internet doing stupid things, most of them are pretty funny. But being Australian I think this one is hilarious, because I know how awful that would be. Basically Vegemite is a dark salty spread to put on bread. Personally I love it, but you have to have it in small amounts because it is a very strong taste. As for eating two jars, that is just insane. Check it out for yourself, have you ever tried Vegemite? what did you think?
