Funny things you've done in video games

Absolutely the ONLY reason to play John Elway's Quarterback for the NES: when running a "Normal" or "Reverse" Option play, throw the ball straight downfield.  A receiver will come out from NOWHERE and have supersonic speed when he catches it.  No one has a chance at catching him.  You can effortlessly run circles around everyone.  Ridiculous!
In Madden '92 or '93, a serious gaffe in the programming allows the ambulance that arrives to pick up an injured player to NAIL any player unlucky enough to stand in its way.  WTF?

Tecmo Super Bowl I'd always use Bo Jackson in running plays who would usually average 50 yards per run.  The first half of the season you could chuck the ball from 80 yards out and always have someone in the endzone.  I'd seriously blow out most teams by 50 points.

When I got bored playing Choplifter as a coin-op in college, I would shoot the hostages coming out of the bunker. They thought they were getting rescued, instead they got massacred.

Test Drive: Eve of destruction needs no reason, it is the reason, as well as Mx vs. ATV unleashed

making a bunch of Lemmings (or whatever the collective noun for lemmings is - probably not 'a bunch') stand on top of each other, then making the one underneath explode itself, so the whole stack of them would go flying

also building a rollercoaster that ends in mid air then making a cart fly off the end. (I think it was Theme Park. years ago)

On Redneck Rampage, I put in a code where the enemies freeze.  I would walk into the fat guys from behind and sometimes they would fart at me.
