Williams wowed by 'kick-ass funny' Vergara

Robin Williams thought Sofia Vergara was "kick ass funny" when they worked on 'Happy Feet Two' together.

The 60-year-old actor recorded the voice of two penguins, Ramon and Lovelace, in the animated movie alongside the 'Modern Family' star - who lends her vocal talents to Carmen – and he admits she had him in hysterics most days.
