The Brady Bunch, Season 5

(Epilogue:
Peter is reading a magazine on the porch, Bobby and Cindy arrive on bikes)

Bobby:
Peter, will you be our judge?

Peter:
For what?

Cindy:
Bobby and I made a bet on who's the best bike rider.

Peter:
What did you bet?

Bobby:
Same thing as Greg and Marcia. The person who comes closer to the stopline without going over wins.

Cindy:
And the loser has to do the winner's chores for a whole year.

Peter:
Well, first you better look at something, Bobby. (points to Greg doing ironing)

Bobby:
Ain't too easy to beat a dumb ol' girl anyway. (leaves)

Cindy:
Chicken.
