At work, I realized ...

• overalls aren't flattering on ANYONE over the age of 3.
• when you switch things up and move stuff around, old people PANIC.
• if you can't pronounce a brand of cigarettes, DON'T smoke them, you'll sound like an idiot asking for them at the counter.
• staring at your money when you don't have enough ISN'T going to make it multiply.
• no matter how many times you try and use your driver's license to withdraw from the atm, you're ALWAYS going to leave empty handed.

That's really all that I can think of now, but I can guarantee I will be adding to the list, sooner or later.
