Fast National ratings for Friday, October 18, 2013.
 
CBS' "Undercover Boss" had a big week -- perhaps America loves Buffet Inc -- and helped the network dominated Friday overall and score a slim win among young viewers.
 
In other words, "Same as last week," only with "Undercover Boss" doing the heavy lifting, which was necessary since "Blue Bloods" was down a little in the demo and "Hawaii Five-0" was down a little in viewers.
 
Risers for Friday included "Last Man Standing" and "Shark Tank," while "MasterChef Junior" came in below last week.
 
On to the numbers, which aren't hugely interesting. Maybe with "Grimm" and "Dracula" premiering next Friday, things will get fun...
