I LEGIT THOUGHT HIS NAME WAS DIACE NOT JOKING-

I'm new on this thing, welcome me

And I found a mistake in a episode.

Dice said in #BlueDogSoda that the bottle could be the last in California, but the soda was probably taken to a secure warehouse that was in California. And the truck still could have gone to many other stores and stuff and when Dice got the bottle, the coulnt have gone that far

When I saw Sam and cat I just laughed my head off every episode
