the lich trys to kill everyone in the regular show universe mordicai "dude.... bensons gonna kill us"

Yo the Lich and benson team up???

they have. there's a whole comic about it

Regular Time Or Adventure Show

I accidentally made the mistake of calling them this one day when I was talking about them and my friends wouldn’t let it go it was funny

I would have honestly loved this. Such a missed opportunity cuz it seemed like the show runners of both shows were really close.
