I like a good shart...
Regarding the blue dress, dont they all dress the same every show? They do that on Dragons Den (UK Version) simply for continuity. After all, you need to find the right number of correct length and correct resulting pitches to fill 1 hour, so its gotta be a compilation of sorts. That way they can cut pitches together how they like and it all looks like one day, even if its actually over a few weeks..
