Bill & Ted's Excellent Cereal commercial (1991)

The Bill & Ted franchise went beyond two films and into two different short-lived TV series, one animated and another live-action.  The cereal was clearly influenced by the former.  It's Lucky Charms, but with more excellentness.

Peter Capaldi is lost in time... and drunk, with Alexei Sayle

Remember that time when Peter Capaldi played a time-traveller on a well-loved British TV series? No, before that. On the second season the the sketch-based comedy "The All New Alexei Sayle Show" aired in 1995, Capaldi played intoxicated sidekick to the similarly inebriated "Young Ones" star in a series of sketches satirizing the "Time Tunnel" TV series. In the first chapter, they stagger around Rasputin as scientist Jenny Agutter (WALKABOUT) looks on in horror.

Evening Entertainment: Jonathan Heap's "12:01 PM" starring Kurtwood Smith

The concept of a person repeating the same time period over and over until they get it right is probably most associated with GROUNDHOG DAY, but Heap's Oscar-nominated short (based on a 1973 short story by Richard Lupoff) considers the idea in the guise of a character drama, with ROBOCOP's Kurtwood Smith as a mild-mannered man who finds himself stuck in a loop. It was remade as a made-for-TV thriller by FOX a few years later, but this is the sort of high-concept, low-budget science fiction short films are made for.

Watch This Thing - 1956 animated short "Mister Wister, The Time Twister"

Mr. Peabody and Sherman weren't the first man/dog team to travel around it time.  Robert Carl Cohen's dialogue-free animated short finds an egg-like man and his dog heading back to to prehistoric times for some rest and relaxation, only to discover that things aren't as great as they are in the present.
