So do y'all know about Curiosity's wheels? They have these cool hole patterns!
The holes are ostensibly for tracking wheel slippage. The pattern is stamped in the Martian sand, and by taking a picture of the tracks and measuring the distance between the repeating hole marks, you can tell how much the wheels are slipping.
But the pattern isn't arbitrary! Curiosity (along with many many other NASA missions) was built by the Jet Propulsion Laboratory - or "JPL". While JPL is entirely federally funded and almost exclusively works on NASA missions, it's technically operated by Caltech, not NASA. When JPL was assembling Curiosity, they added some "JPL" decals to it along with the cool "Curiosity" label on the arm.
Well, NASA HQ found out and got mad. "You can't put those JPL stickers all over our rover!" they said, and made JPL scrape them all off.
JPL reluctantly complied, but definitely got the last laugh. No decals allowed? Well fine - the holes in Curiosity's wheels say "JPL" in Morse code. So every few feet, the name of the real creator of the rover is stamped into the surface of Mars!
