Help me good charlotte fans!

In all the music videos of Good Charlotte i’ve seen, there are five people making music. I can recognize Billy on guitar, Paul on bass, plus Benji and Joel with vocals. But who is the mysterious drummer? I’m stumped… please help

Er. Not really a fan, but from what I remember, the drummer you see is just a backup. The “official” drummer quit before they released their second CD and formed Wakefield. This is the situation the last time I heard. It could be that the drummer joined officially, and if that is… no idea who he is.
