Petrie.

Grass or Sand?

[FallenTreeStar]

” I don't like sand. It's coarse and rough and irritating and it gets everywhere.”

Grass

Ability to view the past at any point or the future 50 years from now?

[ImpracticalDino]

That's a very tough one.

I think viewing the future 50 years from now. Very useful to change the course of present day to ensure bad things don't happen. If I could view the past more than 50 years, I'd probably choose viewing the past instead.

Being a man or a goofy goober?

[InconvenientMoonRising]

We all saw the movie, we all know goofy goober is the right answer

Celsius or fahrenheit?

[ObscuredByClouds]

I'm kind of used to Celsius for measuring Temperature. What else can I say? Should we even have preferences with measuring? 
Sweet or sour?
