Your welcome. I think they show you how to make a tin foil hat also. That's just a joke. The funny thing is that back when I was in high school and pyramids where all the rage, I did make a pyramid hat and I still flunked all my tests. Have a nice day.

HA! Bet your teacher is looking for your essay on how to make theirs now! "What goes 'round, comes 'round!"

I think you're right. I guess they are now 'retro'.
