George Wilson is the elderly next-door neighborhood of a young boy named Dennis Mitchell. Dennis is usually quite careless with everything he does, which usually leads to disastrous results (mostly for Mr. Wilson). Dennis may be riding his bike down the street and not paying attention to what is in front of him. Usually, when situations like this happen, Dennis (and his bicycle) end up crashing into poor Mr. Wilson. In Dennis' mind, he and Mr. Wilson are best friends. In Mr. Wilson's mind, Dennis is the Anti-Christ. Very often, Dennis tends to come over to Mr. Wilson's house uninvited. His visits usually begin with Dennis yelling out "OH, MR. WILSON!" Mr. Wilson tends to consider that a warning to vacate the premises.
