I've always been partial to: "Where's the beef?" or "That's what I'm talking about!" I just love saying those! Which ones do you use?
That's the ticket! Do or do not, there is no try. You keep using that word, I do not think it means what you think it means. "Laser" (with quotation fingers) "A Meeeelion Dollars" Oh and I say "Doh!". A lot.
"That would be telling..." "Frak!" "And knowing is half the battle." "Autobots, transform and roll out!" "To boldly go where no man has gone before." "You're all in the Kool-aid, but don't know the flavor."
Doh! Eeeeexcellent. Do or do not. There is no try. One of these things is not like the others.... Sweet Zombie Jesus! (Futurama) My hubby's favorite (from Ghostbusters) "Mother Pussbucket!"
These, and "D'oh!" are regulars in mine... and I can often be known to exclaim, "Wow, THAT escalated!" whenever something crazy or ridiculous happens.
The French equivalent of "Great Scott!", "Nom de Zeus!" Apparently I say it so many times an hour that my students caught it stat!
It's a freakishly strange thing to say around here (as it is in a foreign tongue), but I have been known to utter the phrase: And so it begins... every now and again. I have no idea where I might have picked it up though, could be from an old 'sandal-movie' or from a more recent teenager-movie (I'm sure it must've been some sort of film (or TV-show)). As a phrase it has the ability to defuse a tense situation and make people start laughing instead of start fighting -which is what I like about it I used to do a lot of my swearing in foreign tongues; loved rolling the r in 'merde' and use German to really put someone in their place. These days English words cannot be used as the people native to that family of languages seem to have a sort of double standard about their swear words and don't like seeing them in print (~on monitor) -so I switched to the more geeky (which is what I love about them) words like Frak and Gorram -which no one around here seem to recognize
"If it walks like a duck, and quacks like a duck... it probably is a duck." "If it ain't broke, don't fix it." And I tend to use "Indeed." quite a lot. There are many more that I use on a regular basis in Italian.
When I hear my name called in my office, my standard response is, "I didn't do it! I wasn't even here that day!"
