Why is it that so many Americans like peanut butter ?

I personally like it because you can eat it at night , and because it sticks to the roof of your mouth,  you can eat some more of it later on. Just make sure not to brush your teeth after you first eat it. This is a great way to have a little something something to munch on in the middle of the night without having to get up out of bed. ;+

  

  Because so many Australians love vega-mite.

  Vegemite is a thick, black Australian food spread made from leftover brewers' yeast extract with various vegetable and spice additives. It was developed by Cyril Percy Callister in Melbourne, Victoria in 1922. 

  The Australian rock band Men at Work refer to a "Vegemite sandwich" in the second verse of their 1981 hit song "Down Under", from their debut album Business as Usual.

They are too lazy to shell the peanuts. 

I have no idea.   It's edible.  Not bad but not good either.   It's great with chocolate though.  Other than that it's like breakfast cereal.  Boring and depressing.
