the skins from peanuts. crack the shells, and peel the peanut (the part you eat) then smoke the redskin lookin things. It doesn't get you high, but it tastes pretty good if you like peanut butter.

I dunno if this counts, but when my buddy's dog died we opted to cremate her (it was winter and we didn't wanna dig in the frozen ground)...we didn't have any gas or fuel to start the pyre, so my other buddy has the bright idea of using cooking oil...we reasoned that oil is flammable at high enough temperatures.

unfortunately, the fire never actually got hot enough for the oil to burn...and the poor corpse ended up fried...I kept looking at my buddies, and I knew they were all thinking the same thing: 'this shouldn't smell good, but it really really does'
