Pretty refreshing to hear the interviewers getting interviewed for a change too. :) Makes you realize there's still a lot you guys haven't revealed about yourself. Backstories and all. So much to dig into. Mabelma seems like a cool dude too.
Regarding those movies/animations where people spoke about their art and promoted NG, sounds like you might be thinking of: https://www.newgrounds.com/collection/mynewgrounds
Good times! And good talk. Till the next one.
Oh and definitely get Souljaboy on here! That'd be more than awesome. He's pretty active right now too. Who knows. Potential promo/NG support at the same time.
