Magoo's Homecoming (1959)

Mr. Magoo thinks he is going to his college homecoming, but winds up in a zoo with a jewel thief as his buddy. He thinks all the animals are his old class-mates, gets a hold of the stolen jewels and drapes them around a bear's neck. The bear give the jewel thief a big, bear-hug, and the near-sighted Magoo ends up as a hero.
