Well, the part about MF is no lie:

Some of the positive things we’ve heard about BC is that he’s a hard worker who goes above and beyond what is asked of him during filming. He’s got a good sense of humor and is nice…provided he’s in a good mood that day which is a lot less frequent since the ShamWow started. Bad things we’ve heard (including set leaks) BC can also be mingy, neurotic, paranoid, snappy and arrogant. He’s developed a bit of a divatude which I hope, for his sake, is temporary…
