John Stamos wanted nothing to do with Mary-Kate and Ashley Olsen in the early "Full House" days, and he in fact got them fired after the pilot was filmed.
The actor dropped the bombshell while on Josh Peck's "Good Guys" podcast, saying he "couldn't deal" with the twins, who were 11 months old at the time of the pilot.

John recalled him and Dave Coulier filming a scene with the girls, both of whom were "screaming."
"They wanted to be anywhere else but there, and so did I," he said, adding that the crew kept unsuccessfully swapping out the twins. "I just couldn't deal with it. I said, 'This is not going to work. Get rid of them. I can't work like this.'"
John said it was "obvious" to everyone that Mary-Kate and Ashley were making the workplace difficult. However, everyone quickly found out that the grass wasn't always greener on the other side after a different set of twins were hired.
"We tried the other kids and it didn't work," he recalled. "I said, 'Bring the Olsens back. These kids are terrible.'"
All and all, the Olsen twins were only away "fired" for a few days.

After John was asked if the girls, now 36, know that he once got them canned from the show that made them child stars, he replied, "They do now." Then, referring to the twin's reported $500 million net worth, John joked, "Now they own this building we're talking in."
Things worked out rather well for the Olsen twins, as they starred in the hit sitcom for eight seasons.
