Here post your stupidest moments that you remember, might be in the past 16 years, might have happened yesterday or in my case, about 2 hours ago.

I'll start off: I did what all PC users SHOULDN'T do, delete the system32 file, had to reformat which took about 2 hours.

Edit: For the love of God, another stupid moment, please someone move this into the General section... Today is not going as planned...
