We examine several resummation methods for computing higher order corrections
to the finite temperature effective potential, in the context of a scalar
$\phi^4$ theory. We show by explicit calculation to four loops that dressing
the propagator, not the vertex, of the one-loop tadpole correctly counts
``daisy'' and ``super-daisy'' diagrams.
