The Wilkinson Microwave Anisotropy Probe has provided us with
unprecedented quantitative information that has helped to establish the
current concordance cosmology. It has also revealed a number of features
that we do not understand so well, prompting suggestions of departures
from the standard framework. In this talk I will review a few of these
interesting anomalies and suggest the most conservative assumption -
that they are due to residual foreground contamination - is the most
likely explanation.
