Yep, many (funny) examples exist. They didn't hold back on this chip though, quite a lot of things added!
Not sure if this still can be done, at least we've been told to refrain from it already pretty long ago. Also increased likelyhood that one of the current checks may flag.
In addition, you got to have a pretty strong story if there's this funny drawing AND some silly bug in the design or layout of the same chip.
