Old Habits Die Hard
As it so happened, Bulk Bicep's New Year's resolution lasted but a single hour. He had decided that this would finally be the year when he would stop saying 'yeah!' to everything every pony told him. This little habit of his was driving away clients from the spa he worked at as a massage therapist, potential girlfriends, and even his family didn't want to be around him for long periods of time. So BB decided that this was the year that he had to try using other words in his sentences. He started small by looking in the mirror and trying to talk to his reflection. But his reflection was kind of giving him a dirty look so he flexed his muscles menacingly at it and screamed, "Arrrr!" before running off. The next creature he tried to have a conversation with was Tom the Rock. Tom was the coolest rock in town. He wore shades as he sat around buildings. That's how you could tell he was one of the cool guys.
BB wanted to show his appreciation towards Tom so he walked up to him and winked. But Tom just kind of sat there, rocking his shades under the afternoon sun. Bulk Biceps shrugged. Tom was just like that sometimes. He could respect that. So he shot a double hoof point at Tom acknowledging his coolness before walking away. The next creature he tried out his skills on was Applejack. But perhaps the Element of Honesty wasn't the best pony to practice with because she kept on bringing up topics he'd have to agree with. Knowing that a 'yeah' might slip out at some point in their conversation, he nodded quickly and got the heck out of there mid conversation, leaving Applejack to scratch her head with one of her hooves and wonder why.
The last creature he tried out his new skills out on was Rainbow Dash. But this was not such a good idea either because Rainbow Dash kept on bringing up sport topics and hoofball play by plays. Mid way through talking about hoofball, Bulk Biceps couldn't take it anymore. He yelled a big, "Yeah!" and pumped his fists a few times open hearing that the Canterlot Dragons won the latest game. He immediately placed his hooves over his mouth when he realized his mistake, and ran off down the road towards his house, leaving a very confused Rainbow Dash behind.
When Bulk Biceps got home he let out a heavy sigh. It didn't look like he'd be able to stop his little habit after all. But he had some solace in knowing that he could always try again next year.
