Need to find these MAD comics that I saw a long time ago

One of them was a hunter coming across very large footprints while following small footprints, running away from them, and then discovering that the small footprints come from a dinosaur with tiny legs, and the big footprints are from a birdlike creature.

Another one was a teenager lugging around boxes of stuff. His parents offer different suggestions of transportation (other than driving) but he dismisses them all because then people will know he’s not old enough to drive and see him as a “little kid” the father thinks he is acting like a little kid.

sounds like sergio aragones little strips, look him up, legend

I grew up with Gaines-era MAD magazine. Most if not all of those artists and writers are dirt now =(
