“If you win a year’s worth of calendars, do you only win one calendar?”

A joke has someone getting “a year’s supply of calendars”—one calendar. The joke was used on the American television sitcom Full House, the episode “The Big Three-O” that originally aired on December 11, 1987:
 
“Danny Tanner, you’ll be riding in style because you’ve won your very own chauffeur-driven limousine for a day. It’s a stretch limousine, complete with a bar, TV, telephone and a year’s supply of calendars: one.”
 
“If you won a years supply of calendars…that would be one calendar” was posted on Twitter on November 16, 2010.

I saw an advert for an art competition where the grand prize was a year’s supply of calendars. Isn’t that just one calendar?

It would be more frightening if you won a lifetime worth of calendars and only won one calendar.

We are only 12 days away from the 30th anniversary of Joey Gladstone telling this same joke.
