  We analytically and numerically study the hydrodynamic propagation of a
precessing jet in the context of tidal disruption events (TDEs) where the
star's angular momentum is misaligned with the black hole spin. We assume that
a geometrically thick accretion disk undergoes Lense-Thirring precession around
the black hole spin axis and that the jet is aligned with the instantaneous
disk angular momentum. At large spin-orbit misalignment angles, the duty cycle
along a given direction that the jet sweeps across is much smaller than unity.
The faster jet and slower disk wind alternately fill a given angular region,
which leads to strong shock interactions between the two. We show that
precessing jets can only break out of the wind confinement if the misalignment
angle is less than a few times the jet opening angle. The very small event rate
of observed jetted TDEs is then explained by the condition of double alignment:
both the stellar angular momentum and the observer's line of sight are nearly
aligned with the black hole spin. In most TDEs, the jets are initially choked
by the disk wind and may only break out later when the disk eventually aligns
itself with the spin axis due to the viscous damping of the precession. Such
late-time jets may produce delayed radio rebrightening as seen in many
optically selected TDEs.
