How to embarrass your brother: 1. Play Britney Spears' 'Ohh La La' in your bedroom. 2. Hide in your wardrobe. 3. Wait for your brother to enter the room and start dancing. 4. Secretly film him and put the resulting video on YouTube.
Unfortunately for the sister in question, however, we have a number 5, which is: See people across the internet applaud your brother's talent and ability to have A Good Time.
Yes, sir, we think we're going to have to add you to this little list...
