The full lyrics:
Fallon:
Only you, every night you throw to me, Jay Leno
In the news, all they do, is say I'm replacing you
They think I can woo
The demo
Leno:
So the network says
Here's an idea
Pack your bags, take a hike
N-B-C ya
Fallon:
Tonight, Tonight
Who's gonna host Tonight?
Is it gonna be Jimmy or Jay?
Tonight, Tonight
Where will they tape Tonight?
In New York? Will it stay in L.A.?
Leno:
Tonight, Tonight
My ratings were all right
Twenty years and I'm still in first place
Tonight, Tonight
I've got Fox on the line
Or maybe I could take over for Dave
Jimmy and Leno:
Tonight, Tonight
Why do they say we fight?
I like you, you like me, we're OK
Tonight, Tonight
Who cares who hosts Tonight?
People just watch online the next day!
TL;DR version:
First, Jimmy showed off his belt.
Then, Jay let it rip.
DIVASSSSSS!
Plus an awkward yet heartfelt ending.
