I actually saw SNL for the first time in a very long time and I thought this skit was kind of stupid as was most of the show like that horrible "Dry Eyes" skit and the "Barry Gibb Show" one both of which were not very funny at all.
The cast and the writing has been at one of their low points recently and this is an example of why. Over it's long history, SNL has its high and lows and they are in one of their bad times now.
I can't stand Justin Timberlake's music but I thought he was one of the better guest hosts they've had in a long time.
