The Venture Bros.

Love-Bheits (2x7)

:

Baron Ünderbheit captures Team Venture when the X-1 crash lands in Ünderland while en route from a superscience costume party. Rather than execute them immediately, he inflicts an unspeakable torture upon them: they're forced to attend his wedding. Only the shadowy, disorganized Ünderground resistance group can help them escape.
