2. That's about it.
I thought that the first OH collab was pretty funny, especially the FLCLmonkey short, interpreting "oh" in a slightly racist but hilarious way. This one had a nice gimmick concept, but it didn't really shine here.
If each segment had a different way of adding "2" to it, I think the response would have been a little better, and the joke would have been a little more elaborate. Nothing much else to say here... even though the OH collab has poor production values, it still has that weirdo charm we could only expect from you guys.
