That I knew about, and it's even fairly well documented; I was
attempting humor about the maybe-somewhat-less-known origins.  (Though
now that I check, those are documented too; see sticky(7) on at least
NetBSD, which also discusses the bit's meaning on SunOS 4, which I
hadn't known until now.)

That one actually isn't a true story; it's just my attempt to break the
question by extrapolating from related traps I know of.  I wouldn't be
surprised if it had happened to someone, though.

(let ((C call-with-current-continuation)) (apply (lambda (x y) (x y)) (map
((lambda (r) ((C C) (lambda (s) (r (lambda l (apply (s s) l))))))  (lambda
(f) (lambda (l) (if (null? l) C (lambda (k) (display (car l)) ((f (cdr l))
(C k)))))))    '((#\J #\d #\D #\v #\s) (#\e #\space #\a #\i #\newline)))))
