User: Do you have an email address?
Me: Really? I'm the IT guy...
User: HELP! My email doesn't work!
*I hurry over to the user's desk*
Me: Ok, let me take a look.
User: Hold on, I have to finish sending this email.
User: I received this email and I'd like you to take a look and tell me if you think it's spam.
*Brief glance at poorly-written email ("You won, Click the open attachment fore downloading of you're free iPad!!!")*
Me: Yup, it's spam.
User: How can you tell?
Me: Did you enter a contest to win an iPad?
Me: Then I'm guessing you didn't really win.
User: But what if I did?!?
Me: You didn't.
And then there's me. I was so tired the other day I was no longer thinking straight. The Boss had asked me to download a PowerPoint presentation from the client's site. I saved the file on my desktop and started to send it to her. I couldn't find it. I looked and looked, but I just couldn't find that silly Excel spreadsheet anywhere...then it dawned on me...
Rat yourself out - what's something dumb you've done lately?
