one of the dudes i work with....he told me he bought a worldwide pure protein bar (only cuz he was starving and no quick "good" food purchase avaible). Now....he took some bites and bit into a solid thing...he chew it out and it was a freakin bone. An animal bone man. (like a chicken bone or somethign very similar to it) Are you kidding me??? I actually have some of the bars at home (i know it aint good source of protein...even for a protein bar, with all the collagen in it and what not) but a bone man?!!!!?! so he wrote worldwide with this and they gave him a 100 dollar certiffate to their site. C'mon though....bone. (in a bar!!)
