Honey, I Shrunk the Kids
Honey, I Shrunk the Science Dude
S1 E5:
Wayne suffers an attack of jealousy when Nick invites Wayne's younger brother, TV scientist Randy Rude the Science Dude, to speak at the school Science Club assembly. At the last minute, Wayne decides to bring along the shrink ray for a little demonstration of his own, but he accidentally shrinks Randy, the shrink ray and himself. The tiny brothers Szalinski end up as prizes in a McDonald's Happy Meal. As Diane and the kids literally dismantle the McDonald's looking for an address, Wayne and Randy escape Play Doh, cha-cha with a chameleon and put aside their sibling rivalry, before they finally get big again.
