I think it was this episode where Marina Sirtis first noticed the the intelligence of her character's dialogue was inversely proportional to the visibility of her breasts.

“There are certain rules in Hollywood. One of the rules is not written anywhere, but you just know: if you’re doing an action-adventure show, you gotta have chicks on the show for the boys to look at when they’re not blowing up other spaceships. Second rule: if the chick has a cleavage, she cannot have a brain.

“So, [after wearing a uniform in the first episode] I got a cleavage, and all my gray matter departed. Which was sad, because originally (I know this is gonna shock you), Troi was supposed to be the brains of the Enterprise. So when the cleavage came, all that left, and I became decorative, like a potted palm on the bridge.”

And when Jennifer Sisko came from the mirror universe, they used the same actor for both those different people... Jenifer Sisko from this universe and Jennifer Sisko from the mirror universe.
