No I won't scroll down to read the punchline to your joke. Not even if you add a thousand "!!!!!!!"s in the subject line. (Especially if, actually.)
Is the "scroll down" supposed to be the textual equivalent of a comic pause? Did you learn this from Strunk & White? Does Shakespeare ask his readers to "scroll down" just before the last pair of lines in his sonnets? Does the Bible have a "scroll down" between the Ninth and the Tenth commandments?
You know why they don't have it? Because it's lame. It's lamer than using "..." at the end of every sentence.
So don't make me press the down-arrow key or click that stubborn scroll-wheel on my mouse. I am this close to carpal frickin' tunnel on my right arm and you must not let your joke be the reason I can't wipe my bottom without wincing in pain. Granted, I may NEVER know why blondes fall off their bicycles at night or why Laloo won't sell his cow to Bill Gates, but we have survived for centuries without penicillin and something tells me we will survive this unfortunate gap in human understanding too.
Brother, I swear on the deluxe hardcover edition of "10,001 Best Jokes For All Occasions" that one of these days, I will send you thousands of punchlines without any setups. Your brain will be clogged with absurd one-liners. Your life will be a Beckettian hell as you wait for a context for each of those funny lines. You will be left thrashing around like a blind man searching for a black cat in a dark room.
I will look at you with mild pity and much amusement as you fall on your knees and beg me to tell you the full story of the one-legged talking horse that participated in a beer-drinking contest in Dublin.
Maybe then you will feel my pain.
