Acting cool at your birthday party when mischievous loved ones are around is a comical mistake, as this video shows. <br /><br />"It was my brother’s 17th birthday, and as you know, turning 17 feels like you’re basically an adult already," the filmer, Ellena, told WooGlobe. "He was acting all grown-up, too cool for everything, and so proud of his birthday cake. Of course, as the amazing sibling I am, I had to humble him a little.<br /><br />"So while he was all smiles, posing for his big moment, my brothers and I gave him the classic sibling treatment... introducing his face to the cake. Consider it a gift to him: a memory he’ll never forget."<br />WooGlobe Ref : WGA302254<br />For licensing and to use this video, please email licensing@wooglobe.com
