Not that I've seen many, but-

Had one land in my hands from a fairly recent previous supervisor who absolutely yanked me around. This from 5 states and 500 miles away.
Tossed it- Karma Rules!

Second one was hand typed from paper edge to paper edge- top to bottom, side to side. Clearly a literal thinker, "Um, keep it to one page..."

Tossed as well.
