1x151 - Tom and Jerry

As Tom and a feline foe attack Jerry, with a fly swatter, bows and arrows and explosives, through different entrances to a mousehole, both become convinced that a supermouse is inside, while Jerry, safely outside, munches on cheese. Finally both cats, having been the object of enough backfiring weapons, decide it's safer to move away. By now the mousehole is in ruins, so Jerry moves out, too.
