This is
what happens to a cat when you stick a post-it on
its head.
A Post-it note is a piece of stationery with a re-adherable
strip of adhesive on the back, designed for temporarily
attaching notes to documents and other surfaces.
Although now available in a wide range of colors,
shapes, and sizes, Post-it notes are most commonly
a 3-inch (76 mm) square, canary yellow in color.
A unique low-tack adhesive allows the notes to be
easily attached and removed without leaving marks
or residue, unless used on white boards...
