Odd One Out, redux

Yay!

Somebody, nobody, anybody or everybody?

I think nobody is the odd one here, because its so negative, while the rest is at least somewhat positive.

For example put the word in the following sentence to get what I mean:

.... would like that.

Everybody. It refers to all of us. Other ones split people into categories.

Anybody, because using the term any- is possible in negative sentence too.

Example: I don't have anything.

'I don't like everybody' is a negative sentence. and 'nobody' covers everyone as well. So LPChip, because his answer is vague enough to not be obviously flawed.

Yay, I guess..

Lets use this forum as a theme for the next odd one out.

Hidden star, Arcade, Avatar or Spoilered text

Arcade, because it's the only feature I haven't used?

Avatar, as it is more an expression of each poster's identity than the others are.

Avatar, because it's the name of movie too.

Spoilered text, it's the part of our posts, not of this page itself.

I like Talps' one most.

his suggestion could've been beaten by the following: Arcade, as the other three are often seen at the same time where applicable.

Oh my, um...

Saturn, Uranus, a monkey, or Neptune.

Monkey, because it's not a planet.

Neptune, because it has seven letters instead of six letters.

Uranus. It's only one beginning with vowel. And only one with nearly horizontal axis of rotation.
