It's here (Gmod tennis)

Im doing a Gmod tennis match with MegaGFilms and MegADX.
I will post my and their video here.
Part 1 (By MrrabbitM/MrIntelM):

Wasn’t anything to do with tennis. unless I’m severely missing something.

Didn’t make any sense.

Boring to watch with silly animation.

A few nice shots, but it hasn’t interested me into watching part 2.

Gmod tennis:
Someone (Person 1) makes a video with an open end. Person 2 finishes this video and that video has also an open end. And then Person 1 finishes that video and so on…

Fixed the link for you.
