Last night, April 26, 30 Rock had its second-ever live show. It featured  several great guests, including Mad Men's Jon Hamm. (Who, we should note, was also in the first live show in Season 5.) It was awesome.

In case you missed it (or just want to relive it), here are Jon's best moments from the East Coast live show — plus a clip of one other awesome, unexpected Mad Men reference.

First, Jon Hamm...in blackface. Don't worry: It was an intentional poke at how racist TV used to be.

Second, Jon Hamm and Alec Baldwin play sexist news reporters (sensing a theme?).

Finally, "Zou Bisou Bisou" from Mad Men’s Season 5 premiere makes an unexpected appearance.
