Sheila Broflovski

"What, what, WHAAAAT?!?!"

- Sheila Broflovski

Sheila Broflovski was Kyle's mother and a major character in South Park. However, she was the tertiary antagonist in South Park: Bigger, Longer & Uncut.

Personality
Even though she means well, Sheila is a shameless control freak and morality-obsessed madwoman who constantly interferes with the town in ways that are often disastrous and detrimental, she views kids as innocent and vulnerable (despite the kids of South Park often being smarter than the adults) and she thinks that even the slightest bit of controversial content will corrupt them.

To this end, she has staged a number of crazy stunts to "protect" the youth of South Park or force tolerance, often taking it to the extremes - she has even tried to declare all-out war on Canada (with the now famous song "Blame Canada") over the vulgar Terence and Phillip movie "Asses of Fire" during Bigger, Longer and Uncut, crossing the Moral Event Horizon.

Sheila's constant ability to vex others and interfere has earned her much hatred from Cartman, who inventively created a song to mock her entitled "Kyle's Mom's A Big Fat B*tch" (unfortunately for Cartman, Sheila's ability to interfere went beyond even his knowledge and she caught him singing the song).
