I have had many jobs but I've always had a good reason for leaving.

I decided to quit my job at...
...Goodyear because it was tiring.
...Midas Muffler because it was exhausting.
...Exxon exploration because it was boring.
...Jacuzzi because the work was draining.
...Delco ignition because it was pointless.
...Corian because it was counter productive.
...McCormick because it was only seasonal work.
