Put on Your Thinking Caps, Kids! It's Time for Mr. Wisdom!

Marty and Verne meet Mr. Wisdom, who hosts a popular children's science show. As it turns out, Doc and Mr. Wisdom were college roommates. Doc doesn't recall it with fondness, as Mr. Wisdom stole his invention for a science fair and won. Things apparently haven't changed as Mr. Wisdom has stolen the DeLorean!
