I wish I had taped it to count them, but Sam and I sat here yelling 'there's one' over and over again. We spotted a lot of them. My favorites were the ones in the factory earlier in the episode.
There were an awful lot of balloons, I wonder if those were supposed to be counted in the 100-150 'official ones.
Did you catch the guy walking down Main Street waering the backwards Mickey Mouse Club t-shirt?
