[Death by Mirrors]

Funny random fact: We have a game show that is completely based around people who claim to be able to do a certain thing (eg. name each different brand of crispbread based solely on the sound it makes when being eaten) and then have to prove it in the show. There's always a couple of these contestants plus one bet that goes to the moderator.
That bet is chosen by the viewers between three possibilities and always works like "We bet you are not able to ___ by the time the show ends". Once a suggested possibility was "We bet you are not able to get a carriage into the show where the horse is sitting in it and the coachman pulls the cart."
Sadly it wasn't picked as that episode's bet. I would've loved to see that.
