Creative DIY Signs That Made Us Laugh
This article was originally published at lizanest.com.

Sometimes the funniest things aren’t crafted by professional comedians—they’re scribbled on cardboard, taped to a fridge, or painted on plywood in someone’s yard. Homemade signs have a special kind of charm: they’re clever, raw, and often way more honest than they should be. From laugh-out-loud protest slogans to silly store displays, these signs prove that humor shows up in the most unexpected places. We’ve rounded up forty of the best examples—each one a little slice of everyday comedy.
#1: Avocado Awareness Board
Office humor can be legendary, especially when it springs from one unforgettable mishap. After a coworker landed in the ER with an avocado toast accident, someone created a workplace sign: “Days Without an Avocado-Related Injury.” Nearly a year later, the tally sits proudly at 320, Post-its keeping score.

It’s the perfect mix of safety-board parody and inside joke. Every update is both a small celebration and a cheeky reminder of kitchen hazards. In a world where avocado toast reigns supreme, this sign turns a painful slip into daily laughter—one safe slice at a time.
#2: A Convention PSA
Not all signs are about politics—some tackle more immediate issues. At a crowded fan convention, one attendee held a poster that read: “If you can afford to attend a convention, you can afford deodorant.” The deadpan expression on their face made the message hit even harder.

It’s funny, blunt, and painfully relatable for anyone who’s braved a packed convention hall. The sign manages to balance humor with a much-needed reminder: personal hygiene is a kindness to everyone. Sometimes the most effective protest isn’t about policy—it’s about public courtesy.
#3: Don’t Scare the Donuts
At this bakery, the donuts come with a warning label—sort of. A handwritten sign taped to the display case reads: “Don’t tap the glass!! (It scares the donuts).” It’s the kind of joke you’d expect at an aquarium, repurposed perfectly for a pastry shop.

The humor works because it’s so unexpected. Instead of reminding customers about fingerprints, the sign gives the donuts a personality. Suddenly, those sprinkled rings aren’t just baked goods—they’re delicate creatures needing care. And honestly, who wouldn’t want to protect donuts from a little stress?
#4: Not Usually a Sign Guy
There’s something extra funny about reluctant protesters. This man, bundled in a hoodie and beanie, held up a cardboard message that read: “Not usually a sign guy but geez.” It’s half complaint, half exasperation, and it sums up how many people feel when pushed to speak out.

Sometimes the simplest words cut the deepest. This protest sign doesn’t list demands or slogans—it just shows that things have gotten ridiculous enough to drag even the quiet types into the streets. When “geez” says it all, you know the frustration is real.
