Hangman!

What day is it?
It is almost 3am here. I am just up for an hour or so then back to bed till 6am.
I have strange sleeping habits..
now are Ü sure there is just one A and only one O??? HMM ?

How about an I?
 
@GD: It's friday here and 10 o clock in the morning,don't worry i have strange sleeping habits too :)
and i'm pretty sure there's only one A,and only one O,I is also correct ;)

_ O I _ _ A _ _ _

No E,S,T
 
and the h of -angman is it in there, or is it out there, I know the truth is out there, but is there also somebody in here? I hope you didn't miss me too much. been kinda busy with nothing really productive...
