Jimmy Fallon married Nancy Juvonen in 2007. They have two daughters, Winnie Rose (2013) en Frances Cole (2014). They also have a female dog named Gary Frick. When puppies are used at The Tonight Show one of them is always named Gary Frick jr.

Blake Shelton: was booked.
While this may not count, there have been a few episodes where Jimmy has said "Stay tuned for Seth Meyers" instead of the usual "Stay tuned for Late Night with Seth Meyers (2014)" right before he high-fived the audience.
