At early times a low mass and/or a high explosion energy is indicated, while at late times a high mass and/or a low explosion is indicated. Several possibilities for resolving the discrepancy are considered. The ejection of ~50 M_sun_ of helium with a kinetic energy of ~2 x 10^52^ ergs, little intermediate mass elements, and ~0.2 M_sun_ of ^56^Ni, might satisfy the observational constraints. The astrophysical site of such an explosion is elusive although a massive star that leaves behind a massive black hole is a possibility. Some problems that make this scenario unappealing are discussed.
