There are probably three things that children and adults agree with.
1. The Muppets are hilarious.
2. iPod Touches are a great way to pass the time.
3. Cake and ice cream can really make a party.
Since the first two items on that list are more recent developments, relatively speaking, one gathers that prior to the 1970s, cake and ice cream’s party-making ability was the only thing that could ever bridge the generation gap.
