When were you blown away by your own stupidity?

I heard a mouse squeaking from somewhere behind my fridge, slamming my first on the side of the fridge would scare it for a few minutes before it would start squeaking again. I pulled the fridge out from the wall, looked all over the back and underside of it, sprinkled borax all over the coils, floor and wall corner, still heard intermittent mouse squeaks, a few days later I layed out mouse traps, still squeaking, pulled it out again, left it out so I could ambush the mouse next time I heard it, upon hearing it I went for the kill and discovered that the axle for a little vent fan on the bottom corner was off kilter and making the squeaking noise, I sprayed it with wd-40, put the fridge back and havent heard it since. This whole saga took 3 or 4 weeks of me infuriated over not being able to kill this mouse
