‘Full House’ Adult Cast Members Were Supremely Immature and Inappropriate On Set

People watched Full House for the kids. Sure, Bob Saget was endearing as the single dad, and everyone had a crush on John Stamos as Uncle Jesse, but it was the cute kids that made the show.

After all, the kids, who are now adults, were the ones starring in the reboot. Fuller House features the Tanner kids all grown up. Now, their kids are the stars of the show.

The Olsen twins, however, decided not to reprise their role in the show. They’ve never commented on why, but Saget’s new book detailing life on the set may hold clues as to why.

Mary Kate and Ashley Olsen landed the role of Michelle on Full House when they were just babies. They quickly became the best part of the show. Michelle’s cute catchphrases had fans cracking up, and the twins shone on screen.

Not many children would be able to perform as these two did, but apparently, the scenes that everyone loved were not easy to shoot. It turns out the girls were average babies. They threw tantrums and didn’t always want to do what they needed to do to get the shot. 

Stamos was so frustrated by the twins that he asked producers to fire them. The showrunners actually toyed with the idea and even had some stand-ins, but of course, it didn’t work out. No other babies could do what the Olsen twins could do, and they were kept on the show. 

Still, being on set with adults who didn’t like them probably wasn’t fun for the twins.

Since Mary Kate and Ashley Olsen and the other child actors were bound by strict child labor laws, they couldn’t be on set for as long as the adults. That means they weren’t usually there for all the rehearsals, either. When they were there, the kids’ scenes had to be filmed fast, which sometimes meant bribes.

When kids weren’t on set, producers used four foot tall rubber doll as a stand in for the kids when something needed to be done while they were off set. The comedians on the show, Saget, Stamos, and Dave Coulter, made inappropriate jokes using the doll as a prop. The men would even go so far as to imitate sexual behaviors with the doll.

While that seems bad, it’s nothing in the long list of inappropriate behavior that went down on the Full House set.

The ‘Full House’ set was no place for children

Pretending to have sex with a rubber doll was actually one of the tamer things that the Full House adults did on set. Coulier, Stamos, and Saget used whippets between takes. That’s a drug found in aerosol containers, and the three men would steal it from props laying around backstage. 

Saget would draw pictures of penises on his notepad during meetings, and then try to get a laugh from his castmates by showing them off. The trio would even take off their pants as a joke and rehearse entire scenes that way.

Although the kids weren’t always on set for these pranks, sometimes they were. Other times they were watching on the monitors. While the kids didn’t understand the jokes, their guardians reportedly would intervene and try to get Saget, Stamos, and Coulier to tone down their inappropriate behavior. Apparently, parents were particularly unhappy about the pantsless scenes, although producers got the joke.
