Zachary Levi was in training for a possible new gig once 'Chuck' is over. 'The Tonight Show' (Weeknights, 11:35PM ET on NBC) followed him as he suited up and got to work at the drive-thru of a local Chik-Fil-A.

Levi was chipping in for charity, and had a lot of fun with the customers as the day progressed. Some of them knew him, which genuinely touched him as he appreciated their enthusiasm and excitement. Others seemed to have no idea who he was.

All they know was this tall guy was acting wacky and crazy. At one point, he told a customer that Chik-Fil-A had the freshest chicken, and then chastised a live chicken for wandering around in the drive-thru. It certainly looked like he was having fun, and bringing it to Chik-Fil-A's customers, too.
