- The only way to find his full name (Other than this page, of course) is by looking at his other channel videos, which usually have a watermark saying: 'Video by: Daniel "Danny" Olah aka TheExtremeUndead.'
- List of his other channels : Danny from TheExtremeUndead, Lyrics Videos, Armpit, UndeadDenny, KylaLaGrangeLyrics, BadCopyCentrala (only for Serbian hip-hop songs).
- His second channel (Danny from TheExtremeUndead) mainly used for songs by Avenged Sevenfold, Limp Bizkit, and other bands that inspired Hollywood Undead.
- He likes to joke about Felix "PewDiePie" Kjellberg, currently the most subscribed person on YouTube. He has stated in a comment that he subscribes and unsubscribes to him on many occasions.
- His girlfriend (Maja Kukic) added effects to the cartoon masks in Swan Songs and American Tragedy. Apparently, according to the Facebook page for his YouTube account, Maja is 3 years younger than TEU himself. It is stated that TEU is around his 20s, so this means Maja is around 15-18.
- It is assumed that he likes old Hollywood Undead with Deuce better than with Danny, but he has said that he likes Danny more because he is in Hollywood Undead now. He also contradicts this one time, where he says he does in fact like old Hollywood Undead a bit more. He seems to treat them equally, and still enjoys Danny.
- He has said that his favorite songs by Hollywood Undead are We Are, I Don't Wanna Die, Undead, Paradise Lost and Dead In Ditches.
- His second favorite band is Linkin Park.
- Hollywood Undead fans said in a couple of times that it will be pointless if his channel gets deleted.
- TheExtremeUndead represented his favorite band all around the world. Still he is not getting any money for his work and he doesn't want it.
- His favourite members are Johnny 3 Tears and Danny.
