Can be anything saw related.
Some of mine:
(recently) Getting a 25 inch bar stuck while bucking windthrow, very embarrassing.
Sharpening a 98 driver chain and screwing both sides of it on a stone on my first cut.
Bore cutting through my hinge and bending my 16 inch bar as the tree fell (was an amateur of 2 weeks at the time)
Getting an 084 stuck in a 6 inch branch above head height. (again, was an amateur)
