Comedian Joan Rivers passed away Thursday at the age of 81 after a successful career that spanned almost five decades.

The Fashion Police host, who broke boundaries in a male-dominated realm, was known for her blunt nature and hilarious one-liners.

"My mother's greatest joy in life was to make people laugh," her daughter Melissa Rivers said after the comedian's death. "Although that is difficult to do right now, I know her final wish would be that we return to laughing soon."

Below are some of Joan Rivers' best quotes through the years:

"A girl, you're 30 years old, you're not married, you're an old maid. A man he's 90 years old, he's not married, he's a catch. "

"People say that money is not the key to happiness, but I always figured if you have enough money, you can have a key made."

"I don't exercise. If God had wanted me to bend over, he would have put diamonds on the floor."

"I've had so much plastic surgery, when I die they will donate my body to Tupperware."

"I enjoy life when things are happening. I don't care if it's good things or bad things. That means you're alive. Things are happening."

"I've learned to have absolutely no regrets about any jokes I've ever done."

"We don't apologize for a joke. We are comics. We are here to make you laugh. If you don't get it, then don't watch us."

"Don't expect praise without envy -- until you're dead."

"You know you're getting old when work is a lot less fun and fun is a lot more work."

"Never be afraid to laugh at yourself, after all, you could be missing out on the joke of the century."

"I have become my own version of an optimist. If I can't make it through one door, I'll go through another door-or I'll make a door. Something terrific will come no matter how dark the present."

"My love life is like a piece of Swiss cheese: most of it's missing, and what's there stinks."

"Yesterday is history. Tomorrow is a mystery. Today is God's gift. That's why we call it the present."

"Life is very tough. If you don't laugh, it's tough."

"When I die (and yes, Melissa, that day will come; and yes, Melissa, everything's in your name), I want my funeral to be a huge showbiz affair with lights, cameras, action. I want Craft services, I want paparazzi and I want publicists making a scene! I want it to be Hollywood all the way. I don't want some rabbi rambling on; I want Meryl Streep crying, in five different accents. I don't want a eulogy; I want Bobby Vinton to pick up my head and sing Mr. Lonely. I want to look gorgeous, better dead than I do alive. I want to be buried in a Valentino gown and I want Harry Winston to make me a toe tag. And I want a wind machine so that even in the casket my hair is blowing just like Beyonce's."
