Wall Vinyl Lettering

When we went to Walmart for some random knick knacks, we stumbled upon the photo frames area where it had lots of wall deco to put on your wall at home. The quotes 'Laugh, Love, and Live' was a popular theme as well as 'Family'.

And have you ever wondered:::  'Damn- THIS WILL DEFINITELY not match his wall'.

PICTURE THIS:
Living Room:
all corners of the wall filled with sports posters.
FOOTBALL
BASKETBALL
HOCKEY

Dining Room:
There is a large screen television with a workout gym on the side. The table isn't a dining table; more like a beer pong table.

Kitchen:
It is so tiny that anymore than 2 people in there is crowded.

Hallway:
You mean that dark area where all our sneakers are kept and no one hangs out there? Yea this could be a 'potential' area for it.

I was looking at examples from websites on where to place them but it would just seem so awkward. Quotes on the wall is DEF a girl thing, or at least a place for a daughter's room. His living space is too masculine. 

I need to balance it out a bit-but I am just not sure where to start and having a quote in a random area in the home won't help it- yet.

HELPPP!
