Sometimes people get a nickname in grade school or grammar school that just sticks with them throughout the rest of their life. These nicknames can be funny in a good-natured way. For instance, an overweight person might be known as "Tiny," a tall person might be known as "Shorty" or a talkative person might be known as "Motor Mouth." Design a novelty street sign for your friend, family member or relative that places their nickname on it and give it as a gift for their birthday or at the holidays. (Just be sure that the individual accepts and likes the nickname that you place on the sign.)
Create a street sign that looks absolutely official, but has a funny saying written on it. For instance, if you live in the woods, rather than a "Deer Crossing" sign, it might be inverted to read "People Crossing." Or, you can create a street sign that kids about someone's intelligence such as "Harvard Admissions Office 1/2 Mile...But I wouldn't bother." Another might entail a yellow "Caution" sign that instead reads, "Caution, Teenage Daughters Sharing One Bathroom," or "Caution, Man Cave, Enter at Own Risk." The nature of the joke sign should again be good-natured and not offend anyone who might see it.
One way to attract attention to a business is to create a funny road sign. It will become memorable in the minds of people who are driving by in their car. For instance, a mortuary might write, "Jones Mortuary...Drive Slowly, We Can Wait." Or a plumber might have a sign that reads, "Tom's Plumbing...We Take the Plunge." Or a dairy might have a sign that reads "Mike's Dairy...Moo-ve Over and Take the Next Exit." The sign should be good-natured and advertise what service the business provides.
Circumstance signs are signs that can be changed or put up for a special event. For instance, if there were a local lotto winner, a sign outside a restaurant might read, "Congrats to Joe and Susan Kelly, for the Rest of You, $9.99 All You Can Eat Buffet." If there has been a local insect epidemic and an owner of a business is not too thrilled, he might take a stab at the lack of action by local politicians with a sign that reads "Welcome to Cockroach Town...Don't Forget to Tip Your Roaches on the Way Out!" Or a Thanksgiving sign outside a restaurant might read. "Happy Turkey Day...Tomorrow, Happy Diet Day!"
