When Markers Attack: A collection of jokes and cartoons from a fitness center message board

"When Markers Attack!" is a collection of jokes, puns and cartoons drawn on a fitness center's dry-erase board. It was originally used by the manager for announcements and some funny "dad jokes". One day an employee decided to enhance the jokes with some cartoon illustrations. It was a hit with the gym members! They really enjoyed starting their day with exercise and a chuckle.
