My lips never know my problem, they just always smile.

Smile if you want a smile from another face.

Appearances matter - and remember to smile.

Nothing left to do but smile.

Even if it's just an hour of their lives, if I can make them feel lucky or make them feel good, or bring a smile to a sour face, that to me is worthwhile.

Whatever you see you gotta keep a sense of humor; you gotta be able to smile through all the bullshit.
