Duke Nukem Missingno.

One rainy night when I was up in my room playing with my brother on Duke Nukem when I was like 6, We were playing it for so long. We were playing Duke Nukem 64 on the Nintendo 64. We were on the level where you started underwater near the beginning of the game and you had to do a code to unlock the passage out of the water and out to land. It was called Toxic Wastedump or something like that was the level name. We were playing around with the dukebots until something strange happened.

When strange things happened
We were going to those screen computers that displayed the cameras but, there was text intead saying: "M'[messed up lines]" I switched the TV off and never played until 3 months later.

M'[messed up lines] is a symbol for missingno. Which means he was not just on Pokémon.
