I discuss some puzzles observed in exclusive $B$ meson decays, concentrating
on the large difference between the direct CP asymmetries in the $B^0\to
\pi^\mp K^\pm$ and $B^\pm\to \pi^0 K^\pm$ modes, the large $B^0\to\pi^0\pi^0$
branching ratio, and the large deviation of the mixing-induced CP asymmetries
in the $b\to sq\bar q$ penguins from those in the $b\to c\bar c s$ trees.
