Young Sherlock Holmes (1985)
Earl Rhodes: Dudley
Dudley : Only seconds left, Holmes. I assume you've given up.
Sherlock Holmes : Never assume anything, my good fellow.
Dudley : But Holmes, I see no sign of a trophy.
Sherlock Holmes : But I do.
[Holmes picks up a vase and prepares to shatter it]
Master Snelgrove : Stop! Holmes, have you gone mad? This is an antique!
[Holmes shatters the vase, revealing the stolen trophy]
John Watson : Dudley is going to pay dearly for this. Punch to the jaw, jab to the ribs...
Sherlock Holmes : Now, now, Watson. Revenge is sweetest when it's served up cold. Come on.
[Dudley enters with snow-white hair]
Dudley : Holmes. You did this. You're responsible, aren't you?
Sherlock Holmes : So that's where I dropped my chemistry experiment: into your tea. Oh, don't worry, old chap. It'll wear off shortly. You should be back to normal - by summertime.
