I use this "-" a lot. Maybe it's a pause, maybe I am catching a breath, or maybe it's because Zim is forcing me to use it.
I have a dark and wacky sense of humor, which gets me into trouble a lot but ends up becoming a pretty good filter. Either you laugh because you are witty enough to understand the jokes or you are accommodating enough to laugh even when you don't - both of which are highly-desirable qualities in a partner.
I have been known to swing a pretty mean carving knife, my head swinging back in maniacal laughter as I rip the damp cold heart out of heads of lettuce and slice, with deadly precision, the eyes out of potatoes. My tortures continue for hours as my hapless victims are boiled in oil, skewered from rump to tip on stakes of stainless steel, pressed against a cast iron brand, flayed to ribbons, and sent to the furnace.
