It's season 4 episode 1. I double checked it and it's just two girls arguing not three and the push is on purpose. It's at 22:40 if you're curious. http://www.dailymotion.com/video/x3j6vxx
Is it Cybill? This forum post mentions a similar incident. http://www.sitcomsonline.com/boards/archive/index.php/t-23413.html
The episode was "Wedding Bell Blues", according to Wikipedia. There would definitely have been 3 women present, though I assume Morgan Fairchild would be wearing a white dress.
What makes you think it was 90210? Edit: Also, in the previous posting of this, Eastopatra gave extra details about the sitcom that the OP incorporated in. Those details did not include the blue dress, but included the two women and the courtyard, so maybe Eastopatra watched the episode of Cybill and mistakenly thought it was the same. This also could mean that the push actually was accidental because the OP originally thought it was an accident.
Edited by jgrif57003There was definitely a blue dress in the show you watched, but maybe Eastopatra watched Cybill and gave you information from that? (You did not mention the two friends in your first post) .That's what I was implying. The main headache with this theory is that it gets rid of many of the details that you added on.
Alexis and Krystal from D Ynasty? Its a pretty famous scene that could have leaked into your memory. https://youtu.be/PfVYaK7VFOY?t=1m50s

Since my old post has over 50 replies, I decided to make them two different posts hoping that it will be easier.
An American sitcom (sometime between the 1960s and 1990s) with one episode involving two friends (both female) at a party with a snobby woman (I assume she's wearing blue) and then they 'accidentally' push the snobby woman into the fountain (which was in a courtyard in the middle of a house, so it was a patio type area), it was at nighttime but really bright as if lit by moonlight as well as the lights of the house. Does anyone know what the show is? And if so, what episode was I referring to?
This has been bugging me for the majority of my life and I have yet to find more information about it. PLEASE HELP ME!
