Thanks Supox. Hopefully one day I'll know all those on my own

[mysterX]

Thanks :)

[bubbagump]

Thanks for the help with the answers. I think everyone only gets five questions, so you might not get all of the questions listed. They will be asked out of order. It also seems that you have the option of choosing a cup instead of a shirt, but I took the shirt.

Thanks,

Bubba

I may have gotten one or two of them wrong, but I think I got them all right. If anyone finds a mistake feel free to correct me :D

I did the quiz again and I only got 5 questions. I wonder why you got 10..interesting.

I think I redid the quiz about 20 times to get all the questions.

[Supox]

The funny thing is that I haven't received my shirt yet.
They probably disqualified me for taking the quiz too many times from the same IP address.

Oh well :)
