1-800-Flowers boss Chris McCann didn't have an easy time being incognito on 'Undercover Boss' (Sun., at 9PM on CBS).

First, in fear of being outed by somebody he's met before, the 1-800-Flowers company president revealed himself to the general manager of a branch. But, just when he thought he was in the clear, Jim McCann, brother to Chris and the CEO of 1-800-Flowers shows up for a surprise inspection.

"He could've called me, he could've just hooked up with me later," Chris said. "Let me do my job." But, Jim said he wanted to "turn up the flames on the degree of discomfort he felt." Ah, sibling rivalry at its best.
