PitchMen Tonight: Just Not The Same Without Billy Mays

Tonight was the first night of Pitchmen, the first show without Billy Mays who died in June, 2009.
It just isn't the same without Billy Mays. It's a nice show and everything, but just doesn't have the fire Billy Mays had.
Sometimes, you just have quit when you are ahead.
The only question I have, since there is a three wait to get a patent now days, don't these inventors take a huge risk going on these shows and having someone stealing their ideas?
