What have I done?

Bob behaved perfectly during our visit to a children's museum today, unlike Sunday's zoo trip. As a reward for his good behavior, I bought him this microphone. It has no batteries but makes his voice echo, which I have to say is pretty darn cool. But he already talks so much we can barely get him to eat. Maybe this wasn't such a good idea...

This is Mr Incredible week 3. I wonder how long this cheap costume will last at this rate?
