I suppose you're joking? So, let's make it into a small lesson on MP
integration. Pretty efficient btw, if you use pdftex. 

% interface=en output=pdftex

\def\EnglishHRule%
  {\setlocalhsize
   \startreusableMPgraphic{EnglishLine:\the\localhsize}
     height = \the\linewidth ;
     x1 = 0 ; x3 = \the\localhsize ; x2 = x4 = .5x3 ;
     y1 = y3 = 0 ; y2 = -y4 = 2.5height ;
     pickup pencircle scaled height ;
     fill z1..z2..z3 & z3..z4..z1 & cycle ;
   \stopreusableMPgraphic
   \noindent\reuseMPgraphic{EnglishLine:\the\localhsize}}

\def\EnglishRule%
  {\startlinecorrection
   \EnglishHRule
   \stoplinecorrection}

\starttext

This kind of fancy stuff is not that hard to do in \CONTEXT,
given that you know a bit about \METAPOST\ support.

\EnglishRule

Why is this called an english line?

\startnarrower
  \EnglishRule
   Is it because they cannot draw a straight one? \par
  \EnglishRule
\stopnarrower

Then, how do germans draw a line?

\EnglishRule

\stoptext

Anyhow, it makes a nice example for the manual. I can package such things
in a mp archive file.
