Barney first figured out that he was incapable of being held accountable when he was paid fifty bucks for stepping on someone's shoe.
"Whoa, sorry, broski," Barney said, trying to apologize to the nice-looking guy whose otherwise crisp white shoe Barney had scuffed. "Didn't see you there."
"No, no, I'm sorry," the guy insisted. "It's my fault. I didn't get out of the way quickly enough. Oh, I must have dirtied your shoe!"
The guy then offered Barney $50, and Barney had no qualms about taking the stranger's money; he just grinned and went on his way after he'd collected the money.
On his way past a newsstand, he tripped and ended up knocking over three display stands. Barney tried to apologize again, but the vendor refused Barney's offer to straighten the display stands, and instead emptied the cash register and gave Barney the day's earnings.
With a bulge in his wallet, a bounce in his step, and a grin on his face, Barney made his way to the bar to meet up with his woman, Marshall and Lily, and Clarence Doucher McLoserface, otherwise known as Ted.
Now, Barney at first didn't want to jump to conclusions, but seeing how he had been paid for his mistakes, he was fairly certain that he could now do whatever the hell he wanted. Sure, he'd had somewhat of an inkling with how Robin had accepted his marriage proposal after weeks of emotional manipulation and lying, but he'd always written it off as his irresistible charm. And his awesomeness. Especially his awesomeness.
Barney, however, was now feeling pretty ballsy, so he grabbed the closest hoe and made out with her and grabbed her booty because baby got back! When the super hot make out session was done, Barney bumped the hoe back onto her bar stool, and he skipped on over to his group's booth like nothing happened. Robin was pissed and she started bagging him about how he couldn't make out with random, busty redheads since he and Robin were getting married soon, but Barney rolled his eyes and pulled out a plastic flower bouquet and said, "Baby, please."
Robin was charmed instantly, which was expected since it had worked like a frickin' charm the last time he'd pulled out cheap magic tricks to distract her after he'd pissed her off. Clarence Doucher Mc Loserface tried to start something by asking Robin how she could put up with that, so Barney pulled out another fake bouquet and said, "Baby, please." Clarence Doucher McLoserface was also charmed.
Lily and Marshall demanded to know what was wrong with Robin and Ted, and so Barney pulled out another plastic arrangement and said, "Babies, please."
With his newfound power, Barney decided to have some fun. He left the bar without paying for his three drinks and order of chili cheese fries-hey, he wasn't going to get in trouble for it-and he spotted a kid playing on a pogo stick. Barney pushed the kid off and hopped away, and the sound of adults berating the kid for not giving Barney the toy sooner followed him while he cackled gleefully.
Barney laughed as he hopped all the way home. He loved being unaccountable!
