Kenya Moore
Who could forget Kenya's first scene on The Real Housewives of Atlanta in season five? She arrived at Cynthia Bailey's burgeoning modeling agency to help judge prospective clients—and was promptly rude and downright insulting to almost everyone who walked through the door, getting off on the wrong foot with the usually even-tempered Cynthia right off the bat. Talk about a first impression.

Porsha Williams
When Porsha was introduced on RHOA just two episodes after Kenya, viewers scored themselves another whopper of a moment. The newbie invited her fellow first-timer to a fundraising event for her family's charity. She then introduced her guest to the crowd by an incorrect title (Miss America, as opposed to Miss USA, which Kenya had actually been named in 1993) and chased her out of the party and into the parking lot when Kenya took offense. The moment ignited a feud that still rages on.

Heather Dubrow
Heather's introduction to The Real Housewives of Orange County was less outrageous and more ridiculous. She met with Tamra Judge, who was still selling real estate at the time, to look at a very expensive home that she was never planning on buying because she already had a ridiculously expensive home that she wanted to show off on camera for a few seasons. It certainly felt forced but got the job done and told us the one thing we really need to know: Heather and her husband Terry are very, very rich.
