The tagline is the short, freestanding phrase that typically appears next to your name when someone is scrolling through a list of prospective dates. Writing something brief and funny in this space can attract someone with a good a sense of humor who's looking for a partner. For example, you might use a humorous and/or famous quotation such as, "Trying to be fascinating is an asinine position to be in" -- Katherine Hepburn. Change your tagline often to keep it fresh. You might also try reworking a famous advertising slogan such as “Don't leave home without me.”
Hobbies and Interests
Most online dating sites have a section where you can provide some information about your interests. This is a good place to showcase your sense of humor. Write about your real hobbies and passions, but do it in a funny way. For example, instead of saying, “I like to fish,” say, “All the time I've spent fishing has taught me that even the best line gets weak if you use it too often.” Instead of saying, “I'm an Information Technology Technician,” you might say, “I'm an IT guy, but I won't fix your computer until at least the third date.”
Keep in mind that it's possible to be scrupulously honest and still funny. Add a little humor to your description of yourself by tweaking any stereotypes that may apply to you. Try something like, “Blondes may have more fun, but being a brunette, if we have fun, I'll still remember it the next day,” or “I'm a manly man, but I will eat quiche on occasion and may even share the remote control once we get to know each other.”
Most people want to appear as attractive as possible in their dating site photographs. Use your profile picture to show that you are cute and funny, too. Post a photo of yourself up on stage at the local comedy club, or perhaps, posed to resemble a Weird Al Yankovic album cover. Wear a pair of oversized sunglasses or “draw” a moustache on your picture with a photo-editing program. Again, change your photo frequently to keep things fresh. Choose photos that make people laugh but also intrigue them enough to want to learn more about you.
