It's but a couple of weeks away, and "The Tonight Show" will have a new host, Jimmy Fallon, replacing Jay Leno.

That is a daunting task, following in the footsteps of Steve Allen, Jack Paar, Johnny Carson and Leno. 

The stress must be huge.Well, I guess Jimmy is a bit scared about leaving "Late Night."

Luckily, the men of '90s sitcom "Full House" were on the show last week to cheer him up and get him through it.
