  This depends a lot on where the drop is.

  If it's falling freely (ie. a raindrop), then its shape is close to a
lemniscate or like a hamburger-shape (although it depens also a lot in the
size of the drop).
  If it's sliding on a surface (eg. a window) then it gets more the classical
teardrop-shape. The upper part may or may not be sharp, depending on the
physical properties of the surface.
  If it's hanging from a surface (being about to drop), then it's also like
the classical teardrop-shape, but the upper part is more like a hyperbola.
