Cynical minds may say the nicotine-huffing stars of Mad Men—Bryan Batt, Rich Sommer, Aaron Staton and Michael Gladis—dropped by the Soup to push the new season of their show.

On the other hand, maybe they showed up just because it's so darned fun hanging out at the nonstop party that goes on here at Soup headquarters. That, or they were only trying to locate LeVar Burton.

This and many other questions may or may not be answered on your fresh serving of Soup tonight at 10 p.m. ET/PT.
