Something you would have written on a T-shirt.

[SoulIsTheGoal]

"This is a t-shirt"

I like things to be clearly labelled.

 

[necromanzer52]

The angels have the phone box.

 

[Wondermint13]

Words on a shirt!

This guy gets it!

 

[spectrenihlus]

I'm not a space cadet.

I'M A SPACE ADMIRAL!

 

[Ohhi]

" Like making babies from a candy mmmm..... candy."
Or
Guy 1 "I'll smack you upside the head"
Guy 2 "yeah well I'll put my ass in your lap... wait what."
Or
Guy 1 " Pizza sounds good right now"
Guy 2 "your right penis does sound good right now."

"Go ahead, be negative, you'll be just my type".

...Sorry, I need to post that somewhere, even if negative isn't my type.
Cookie for reference, of course.

In all seriousness, I don't think I'd want to print my motto on a T-shirt, as it's hardly something that can be called endearing.

Edit: Or this:

"Haters Gonna Hate"

While walking around wearing socks with sandals...

One of two here.

Printed inside a post it note "I owe you one funny t-shirt quote"

"Last chance for Love"

 

[octafish]

Rudyard Kipling's If-- in it's entirety.

 

[Ironic Pirate]

(an up arrow), The Insecurity, (a down arrow), The Reason.

Nothing like good ol' self deprecation.

 

[Naheal]

"Jesus, save me from your groupies."

I would also wear my cross with that shirt.
