If you're like us and value your sleep, you probably nodded off into your Ambien dreamland before the party started on post-prime time TV. Don't worry; we've got you covered. Here's the best of what happened last night on late night.

It's that time of the month again: where Jimmy Fallon lets his celebrity guest on "The Tonight Show" (in this case, Kaley Cuoco-Sweeting) play with a bunch of puppy labradors. Nothing else matters. Only this.

In which Jimmy Kimmel introduces "Lullaby Ben" (a sleep machine), and says that Ben Carson comes off as a "guy who grabbed the wrong drink at Bill Cosby's house." Just leaving this here...

Trevor Noah visited Stephen Colbert on "The Late Show," and did his best impression of GOP candidates at the debates. It scary-good. Emphasis on scary.

As everyone knows, James Cordon, in which they out-grunted each other.

Finally, Big Sean did a parody of "IDFWY," and it was basically adorable. Look at that smile!
