If you're not someone who likes to be surprised, momentarily confused and then laughed at, you probably don't love feeling like you're constantly on a hidden camera reality show in your own home. Finding a partner with a sense of humor is a priority for most people, but there can sometimes be a fine line between being funny and being mean-spirited.
If the person you're "pranking," isn't laughing, then your joke is just bullying. That can be a tough lesson to learn for the family clown, but a big part of cheering up your loved ones with your comedy skills is knowing how to read the room. If your wife has a baby on her hip, you're running late, and she's processing the fact that she's about to spend an indefinite amount of time dodging digs from your mother-in-law over bland pasta salad, it might be a good idea to skip the "hilarious" practical joke.
