  We analyze idealized sequential Stern-Gerlach experiments with higher spin
particles. This analysis serves at least two purposes: The widely discussed
spin-1/2 case leads to some misunderstandings which hopefully is removed by the
higher spin discussion. Secondly, Wigner rotation matrices for generic spins
become conceptually more transparent with this physical example. We also give
compact formulas for the probabilities in terms of the angle between the
sequential SG apparatuses for generic spins. We work out the spin-$1/2$,
spin-$1$ and spin-$2$ cases explicitly. Since there are some confusing issues
regarding the actual experiment, we also compile a "facts and fiction" section
on the SG experiments.
