The Jake and the kid from The Bill Engvall Show stuff was completely ripped off from a Family Guy episode where the gang tries to mimic stunts from Jackass (including the shopping cart ride off the roof.) I do like that they tried to do something with someone other than Charlie on this show, but this is not the right way to do that.
As for Rose, I am glad she was back on the show, but Charlie falling for her plan? Really? I'm not buying that. The stuff with the mannequin just felt very childish in my mind too.
Not a bad 2.5 Men though.
