3 toed sloth

Mycroft has heard worrying reports of laziness in workplaces which are meant to be Buzzing Like Angry Hornets that have become Very Angry.  Mycroft has thus been motivated to attempt to think of the best (worst?) description of lazy behaviour.  The early favourite was:

"Would not work in ten iron lungs"

A few other potential front runners include:

"Slower than an arthritic snail" and
"Slower than an arthritic 3 toed sloth"

A winning combination would appear to be:

"Slower than an arthritic 3 toed sloth in an iron lung"

Readers are encouraged to send in descriptions of Lazy Sloths they have witnessed pretty much anywhere.  The most Slothful Arthritic Snail identified will receive a handsome reward of Nothing.  The nominating reader will have the satisfaction of spotting a Dreaded Sloth.

Well done all.
