“I had a dream that I was a muffler last night. I woke up exhausted!”
Dad jokes. It's usually not a compliment to your sense of humor when the word dad is assigned to your joke. What it usually means is that your joke is "lame", overly punny, or just groan inducing. But you know what? My mom taught me the fine art of puns. Dads are just saying what everyone else is thinking but with more word play involved.
Luckily, the internet seems to be a receptive environment for dad jokes. Memes are usually just dad jokes playing off of some pop culture reference. Hooray for memes!
