Pop! goes the Stash.

In the latest episode, the Comic Book Men visit the grand opening of the Funko headquarters in Washington.

Funko has adapted a seemingly endless number of pop culture characters into Pop! vinyl figures, and now the Comic Book Men are among the chosen few.

Follow along as they get the inside scoop on what Ming calls "a fan boy's dream" in Funko's new megastore -- and don't miss the look on Mike, Bryan and Ming's faces when their Pop! figures are debuted for the first time.

Plus, Rob Bruce fills in for Mike, Ming and Bryan at the Stash. Can this trainee stand the heat behind the counter?
