The last time I read anything about Takki's waking habits was about 2 years ago
That he gets his wake-up calls
from Manager-san. Apparently, things hasn't changed much in the house of Takizawa 
Manager-san would wake me on my keitai. 20 minutes before he comes to get me ne. The ringing sound ne, is Darth Vader theme song (laughs) Jyaーn jyaーn jyaーn jyaーjyaー..... like that ne. 
I'm wondering if he's actually referring to the Star Wars opening, or the ACTUAL Darth Vader theme
If you're wondering what the Star Wars theme vs Darth Vader theme sounds like, you can check it out

Actually in the beginning I really did thought he was just referring to the infamous Star Wars fanfare, but then I thought, hey
maybe Darth Vader really does have his own theme (d-uh)
Found that website and downloaded that midi and OMGWTFROFL YES IT'S ONE OF THE MANY FAMILIAR BGM SOUNDS OF STAR WARS BUT.....
THAT IS ONE HELLA CREEPY SONG TO WAKE UP TO!!!
こーこーこわい じゃん?
And seeing from the "verbal description" of how the song goes, it kinda does sound like he's referring to the actual Darth Vader theme instead of the Star Wars opening fanfare
Actually, I don't know. Don't listen to me *LOL*
My alarm clock is in my keitai too btw, and since I'm quite a piggy sleeper
(a snooze button is ESSENTIAL because there's no way I'll be able to drag myself up immediately after the first ring)
And I need the loudest most annoying sound to wake me up
but OH GOD PLEASE!!!! NOWHERE NEAR ANYTHING THAT CREEPY!!!
*LOL*
Takizawa, YOU変な小父さん 
Hmmm... so MANAGER-SAN picks him up every morning.......... hmmmm....
