Whoops, I should probably add one too.
I am so lucky to have moved in with my cousin in Chicago. I feel like doing the dance of joy!
Schillinger from Oz?
Balky!
I guess I should contribute one, too.
I’m a spunky feelance journalist who travels around with an odd fellow and his metal dog.
Affirmative.
Heh, I was going to add “Ha! I kill myself” in there, but decided it was already easy enough (though I tried to be tricky with the whole Mrs. Ochmonek/Jerry Seinfeld thing 
)
I was incredibly wealthy.
Through no fault of my own, I lost everything and ended up mooching off a hooker.
I regained my wealth (and more) through an incredible feat of revenge.
Who am I?
Dan Aykroyd in “Trading Places”
I spend all my time as a glorified telephone switchboard operator in outer space, while my four brothers get to fly around the universe, saving humanity. Damn, it’s unfair!
Yep!
Could be worse, Ms. Smith. At least you got to keep (a version of) the dog.
By the way, I hope you got rid of that Andy Pandy outfit…
My effort:
I fought in Vietnam. I dragraced hotrods. I was a pilot trying to survive breaking the speed of sound. I was the King of Rock & Roll. I’ve been a priest, a mine inspector, a blind piano player, a community theater actor. I’ve worked with Marilyn Monroe. I planned the Kennedy assasination. I saved Jackie’s life. I have a medical degree. I have perfect recall. I’ve been a mentally impaired youth. I was a civil-war veteran. I was a high-school basketball player. I was a pregnant woman.
I just want to go home.
(yeah, I know, I made it too easy.)
Sam from Quantum Leap
I am a pickpocket who escaped from prison, only to be captured by a soldier who wanted me to go back inside!
Eek! It’s a “Mouse”!
He built it. I came…later.
Dammit, I cannot stump you guys!!!
You’re either Shoeless Joe Jackson or Kevin Costner’s father.
My fiance was murdered for bank password codes by his best friend.
Phillippe the Mouse, played by Matthew Broderick in Ladyhawke.
On preview, I see I was beaten to that one.
My father didn’t speak to me for years because he objected to my choice to join the military instead of staying home and studying science. But my travels in the service have brought me true friends and eventually led me into my father’s line of work.
Demi Moore’s character in Ghost?
The latter is the one who came later. 
Indiana Jones.
