If you’re a longtime reader of my blog, you’ll know that AIs are consistently terrible at humor. Whether it’s a very simple neural net learning to tell knock-knock jokes, or a more-sophisticated algorithm trained on tens of thousands of short jokes, they tend to get the rhythm and vocabulary correct, yet completely miss the point.

In a previous experiment, I trained a simple neural net on a collection of April Fools pranks and noticed that most of them end up being pranks you play on yourself. Figuring that this sort of solo prank might be useful for this year, I tried a much more sophisticated neural net, one that didn’t have to learn all its words and phrases from scratch. The neural net, called GPT-2, learned from millions of web pages. Using talktotransformer.com, I gave it a short list of pranks and asked it to add to the list.

Here are some of the neural net’s suggested pranks.

Put a large, colorfully wrapped strip of spaghetti in your hot water bath. Put some dill pickles in there as well.
Spread the jelly eggs on the toothpicks to attract the jelly eggs.
Using a sledgehammer, smash up a handful of raisins and then put them on a tray.
Put a wad of toilet paper into the bottom of the refrigerator.
Put your fear of insects into a lemon.
Tear up a roll of toilet paper and make toast out of it.
No time for a snack, just draw a heart on the egg carton.
Paint the fridge with the red spiders
Glue toothpicks to the tops of grapes.

Self-prank? New hobbies? Performance art?

It often seemed like the neural net thought it was supposed to be doing its best to suggest recipes or lifehacks.

Step 10: Fun in the Shower
Fill your bathtub with cold water.
Take the jar of sawdust out of the freezer.
Dump it into the water and stir to add some texture.
