Most of mine are from when you repeatedly select a unit.
Battlecruiser (SC1):
I really have to go, Number One.
Battlecruiser (SC2):
"Let's go this way really, really fast! If something gets in our way, shoot it!"
(Possible Better Off Dead movie reference)
"Let's hurry up and finish this attack, it's raid night..."
"What's with all these blinky lights?"
"Flying this low always makes me nervous."
"Do svidaniya. Don't get any on ya!"
(Do svidaniya means "until we meet again" [basically])
"I've lost my hat! Swing around, we'll pick it up."
(Possible Hot Shots! movie reference)
"We're going down. Stay with the ship. I'm out! Where's my escape pod?"
"I'm seeing double! Shoot them both!"
"Ah, it's happy hour. Wonderful!"
"What do you mean we're out of olives?!"
"I have an announcement! I am drunk!"
Diamondback:
"Haaah... the open road, wind in my hair, universal domination."
"Yes, in fact, I do own the road."
" Not all who wander are lost... some of us are drunk."
(Possible reference to the poem named "All that is gold does not glitter" by J. R. R. Tolkien)
"I completely respect your opinion, as long as you keep it to yourself."
"I don't suffer from insanity... I enjoy it."
"My reputation precedes me. Otherwise I'd be late to all my appointments."
"Ah, the open skies, wind at my back, warm sun on my... wait, where the hell am I?!"
"Have you no shame? Good, neither do I."
"I'm a compulsive liar. It's true, I swear it!"
"Revenge is a dish best served cold... to someone who's already dead, because you killed him, out of revenge."
