*sigh* i know, but when your girl likes those gay bands you have to pretend you are intrested in her intrests =(.
I'm sorry if it offended you, i know i hate them too.
Edit: Your post opened my eyes, and i deleted the jonas brothers video for great justice. I'll deal with the concequences later when i visit my gf lol.
Or you could just tell her that you are jealous, and she has to decide between you and the jonas brothers 
Edited:
I somehow ended up adding this video to my favourites now, because I like the song and Gmod, and this combines them both :P
