You'll Shoot'em Down Because You're Waiting For Someone Good To Come On

So... the hosts of The Tonight Show have been, in order: 

Jack Paar

Johnny Carson

Jay Leno

and Jimmy Fallon.

Notice anything about that lineup?

All their first names begin with J!

Coincidence? I think not.

EDIT: I was informed that the first Tonight Show host was actually early TV comedian Steve Allen, and I had forgotten about Conan O'Brien's nine-month stint as host after Leno's first 'retirement'. So the theory may be Jossed. Let's wait twenty years and see who succeeds Fallon.
