"But -- "there shouldn't be any reason why we couldn't move around in time like we can move around in space" is just wrong. There's a perfectly good reason, namely that there is only one direction of time, while there is more than one direction of space."

We might need to change our sub-head in Natter from:

"Wanna talk about corsets, duct tape, or physics?"

to

"Wanna talk about Vicar potatoes, puppycam or physics?"

"Awww, that's just a bunch of Vicar potatoes!"

I think the arrow-of-time problem is why my head explodes when i watch Terminator movies.

"Awww, that's just a bunch of Vicar potatoes!"

"How would you like your vicar potatoes?"

"Poppycock and Vicar Potatoes!"

"How would you like your vicar potatoes?"

Well, I know I don't want ass potatoes.

Well, I know I don't want ass potatoes.

So not browned, then....

I wonder if it was one of those big baking potatoes or one of those small yukon gold potatoes.
