At least one of the Dragon's Den cast is sane. I've seen some pretty weird things from Deborah Meaden on twitter.
As an aside, have you ever seen the video of the guy interviewing women on the street about whether 12 year olds should be allowed to get tattoos and they all say no, they should wait until they're older before making permanent decisions about their own bodies?
He then asks them the same question about puberty blockers and they all say the complete opposite without seeing the irony. Scary, the thought processes of some people.
