Good one, always_bezee. I'd say save that one until the second date. I'd say when its time to pay for dinner.

hmmm..... total WAG here... I'll guess a dime is about 1/2" diameter, and a quarter is about 1" diameter, and figure the grooves are about 1/32" apart, so my guesses are: dime => (.5 * 3.14) * 32 = 48-50 grooves quarter => (1.0 * 3.14) * 32 = 96-100 grooves with the variation being whether they groove them based on a decimal or binary system. :)

~I'll go with the Guinness Book of World Records - just something prophetic about it. Either that or The Caterpillar Book. We have 3 libraries in our community but only one copy of the Bible between the 3 of them. Maybe the others have been stolen!

Dumbass here.....no clue. Last time I saw a periodic chart was 8th grade. You think I can remember that far back? Piffle.....No answer from me. Jasdip, if I was on line yesterday, I would have given the correct answer along with a bunch of goofy ones. Oh the fun I would have!!!!
