T-shirts on parade

Okay, I was puzzled.

I was in the city today and a tall young man walked past me wearing a T-shirt with the following legend printed across the entire front, in large friendly letters:

CAREFULLY
NURTURED BY A
BLUE-FINGERED
GENIUS.

I'm guessing it has nothing to do with intelligent Andorians, but if you have any insights, please let me know. (UPDATE: Solved.)

I mean, I can understand most T-shirt messages. I liked the one I saw the other day, which had miniscule writing in the centre of the chest area that said, "If you can read this you're standing too bloody close." My only complaint with that one was that they expected people to pay just as much for it as others that used much more screenprinting ink.
