A plot of Sign[x]

I tried to plot the Sign function, making clear that Sign[0]=0 by typing
Plot[Sign[x], {x, -5, 5}, Mesh -> 51, PlotRange -> All]
Making Mesh an odd value shows x=0.

But the point at x=0 is being plot as 0.5 in stead of zero.

What am I doing wrong?

Mathematica 6.0.3 Linux x86_64
