NEW YORK (AP) — Fans of newspaper comics will instantly notice something missing in many of the strips this Friday — pants.

More than 25 cartoonists behind strips from “Blondie” to “Zippy the Pinhead” are celebrating the quirky holiday No Pants Day in a way that helps charities get clothing to those in need.

Participating artists are drawing their characters without trousers and urging readers to donate old clothing to thrift and second-hand stores hard-hit by COVID-19.

Cartoonists were contacted in February about the project and the finished comics started to come in by March.
