F'ing suuuuuuuuuuuuuuuuucks.

Damn he was my favorite on the show. RIP Grant 

Wow, sad to hear. I loved Mythbusters and the stuff that he, Tory and Kari did. More so that what Jamie and Adam did. 49 is just way too young. 

RIP 

I had no idea he was that old.

Cool and very smart dude... sucks RIP

 

 

A friend of my wife's, worked with him. She was posting all over fb about him passing before news broke.  Sad stuff.  

Terrible news. RIP Grant.
