Few years ago I got an "ad" that was just some dudes really bad call of duty black ops 2 sniping montage.
I mean full on some of the most meh trickshots and quickscopes I think I've ever seen, against the built in AI opponents that you can enable in custom games, something like 5 or so years after the game was actually relevant to pop culture.
Someone forgot to sign off when using a computer in the computer lab, and by using google chrome you could change the desktop wallpaper. Some unknown person changed it and signed the computer off. The next time that kid used that computer he signed on and was immediately greeted by full on furry porn, with exposed nipples and ass in full view of everyone including the teacher.
The closest I personally got to messing with them tho was just me installing and playing Tony Hawks Underground 2 when I had the chance.
