"Dibs?"

So our friends Keys, Joe, Shelby and I were going to lunch one day, but on the way we had to stop by Shelby's bank so she could cash her check. Shelby and Keys ended up going in the bank and Joe and I stay in the car to wait for them. Joe and I were people watching, which we do quite frequently, and I noticed a familiar truck pull up to the bank, and an old man gets out, I proceed to say "Oh my god" and I hide my face. My friend Joe then screams "DIBS!" and lets out this freakin LOUD laughter...All I could do was stare at him, and I finally got the words out: "That's my grandpa!" and to follow, more boisterous laughter...So a few minutes after Shelby and Keys make their way back to the car, and Joe tells them of the event that just took place, and Shelby asks; "So did you take back your dibs?" and Joe, with a shocked look on his face screams "HELL NO! I WON THAT ONE!"...This sh** my friends say.
