Oh that reminded me of others (but only the one I wrote was a shot of real exam paper - others sounded to be just jokes):

1/n sinX = 1 siX = 6 (prefixed with note:"a blondie solving equation")

sqrt2/2 = sqrt

lim x->8 = 1/x-8 = "infinity sign"
then:
lim x->5 = 1/x-5 = "5 rotated 90 degrees"

(imagine drawing) On a perpendicular triangle sides are 3 and 4, hypotenuse marked with x.
Q: Find x
A: (draws a circle around x with a note "Here it is")

To me they looked like creative jokes rather then being real:)
