Were these movies directed by Penny Marshall or Ron Howard?

It's pretty crazy to consider just how much culture emerged from Happy Days. Two of the biggest directors of all time worked on the show. First, obviously Ron Howard was Richie Cunningham. But then, seasons later, Laverne debuted on the show, before Penny Marshall anchored Laverne and Shirley. 

So, all this talent under the same lights... We want to know whether you can tell them apart! We'll list a movie, you tell us which Happy Days alum directed it. 

Good luck, and be sure to share your score (and your favorite of these movies) in the comments section below!
