Also notice how the presenter first says "we're going to make sure that Chris is OK", and then "we're going to make sure that Kevin's OK"!
I noticed this too! Although she refers to him as Chris twice... perhaps he's really called Kevin but they secretly use him for loads of stuff and make him wear wigs and change his name.
Her co-host is called Kevin, the guy who can't figure out a ladder is Chris. I don't think it's anything more than her getting their names mixed up - when she calls Chris Kevin, Kevin says Chris to correct her.
