It's Bruce Willis' 70th birthday today; in celebration, what are your favourite Bruce Willis roles or movies?

As the title says. I just discovered that Bruce Willis turns 70 today and thought I'd ask the r/movies community what everyone's favourite roles or movies are... I get the impression that I know what a lot of people will choose, but he has 147 acting credits (as per IMDB).

As an aside or addition to the question, what are his most underrated roles or movies?
