Most annoying misquotation?

[Fenton]

Yeth

[Westmarcher]

I sought tho. Sanks Sankth.

[Duke Speedy of Leighton]

"I'll see if there's a window in my diary!"

And people who insist on focuses instead of foci!

[Vamboozle]

'Let's touch base"

Going to touch your base with my fist in a moment.....

[getagrip]

Seems we're going down a "annoying things people say" route so:

With all due respect... Usually means they have and show none!     

[fsn]

'Let's touch base"

In my ruleset, that means you've entered hand to hand combat.

[Luddite]

Ah, well, if it's annoying phrases...

'24/7'   

'On a daily basis'   

'Going forwards'   

[getagrip]

In my ruleset, that means you've entered hand to hand combat.

[mollinary]

"Wherefore art thou.........x?"   As if it means "where" rather than "why" which is what it actually means!!   

Mollinary

[Westmarcher]

Yet, somehow, "where" seems just as appropriate. "Where are you, Romeo?" (as in, "where does your allegiance lie? Are you with the Montague's or the Capulets?')  

Interesting to know, nevertheless, Mollinary.

[Ithoriel]

"Deny thy father and refuse thy name;
Or, if thou wilt not, be but sworn my love,
And I'll no longer be a Capulet."

She doesn't care where his allegiances lie

[Nosher]

"Elementary my dear Watson."

Never, ever written in any of the books...

[Duke Speedy of Leighton]

But he does ejaculate frequently at Watson!

[Nosher]

Most annoying phrase?

"We're all in this together....    "

[Techno]

"Elementary my dear Watson."
Never, ever written in any of the books...

Anyone know where that originated ?
One of the films ?
