Shottr, a macOS screenshooting application I use all the time while working, randomly put #Clippit, the MS Office paper clip, on top of the screenshot window with a request to buy the application.

I was genuinely both surprised and thoroughly amused by this and proceeded to immediately purchase the Friends Club license.

#Shottr is a good app. Free to use. Makes it really easy to make and drag screenshots into mail, teams and more. Very much recommended.
