I don’t know what kind of revenge you think you passed up. How is you acting like a fool at the checkout supposed to “embarrasses” the clerk? Is the idea that she would be embarrassed to be acquainted with you?
You sound petty and barely literate. Even if you don’t teach English, remedial study is in order.
Mildly disrespectful but archaic enough not to need taking very seriously. 
I wish to apologize for this thread.
Yesterday, I had my family visiting me and my 13 year old brother who happens to enjoy pranking people was on my laptop. He told me he wanted to check imgur and I was more than happy to lend him my laptop.
I had my straight dope account open and he created the thread. I found out last night while checking my email. Currently he is grounded and in a few hours I will speak to him about his actions. I have no idea why he did this and I am upset at him.
Once again, I was foolish to leave my account open and I am truly deeply sorry.
I’m not buyin’ it.
A 13 year old, unfamiliar (I’m assuming…) with The Dope wrote that?
Nah.
But I buy your apology. Not like you owe me one. But I understand poster’s remorse.
I’ve been there myself. You’re good.
(Don’t let it happen again, or The Hounds will be unleashed.)
Ah, good response! I have a 12-yr old, and if he made a “prank post” there would be numerous references to “poop”, “Poopy-Pants”, farts and Minecraft. Not to mention an elaborate revenge scenario.
Not buyin’ it.
Even if your story’s true (which is doubtful) you really shouldn’t have said anything. Siblings are supposed to cover for each other.
Unless, you know, he was getting revenge on you for something.
This makes no sense as a prank, so I’m not buying it either.
No problem.
I’ll go ahead and close this.
