pulling pranks on boss

worked at advance electronics in winnipeg, manitoba, canada for 5 years. In my last year got fed up with our boss pulling his personal vehicle into the shop and leaving with the keys. We need to get cars moved around and he causes many headaches doing this. So this time he left with keys and i went into his car and duct taped his clutch and brake pedal together. Figured he wouldn't make it out of shop just keep stalling car. Nope. He drives fairly fast. He zoomed out of shop, started for the main road and just before he went into the busy lanes, he stalled. He almost made it into traffic. He raced back into shop while we were all rolling in laughter. He almost decked me for doing it and i don't blame him. It was a pretty serious joke that may have crossed the line. Not to long after i got fired, it may or may not have had to do with it. Don't mess with the bull or you'll get the horns is the moral of the story. 

That's not funny at all and you could have killed him.  Not a professional stunt, my friend.
