A little bit aggravating
I think I was put off by the way that you made the second character, supposedly Mr. Blue's friend, just as incredibly idiotic as the annoying guy. You'd think that Mr. Blue would have the sense to pick some friends who were actually intelligent and/or sane; otherwise, why is he yelling at Mr. "Actually", but not at a guy who comes to his own conclusions regardless of what other people say and also bursts into tears for no reason?
I liked the straight dialogue with Mr. Actually before the friend came in, and I liked the senseless bit with the rock afterwards, but I just don't think the friend makes sense in any way. I suppose it's random, but I think it's too random - after all, you already have clay people, an "Actually" man, and a talking rock.
