  In this note we compute the topological Hochschild homology of quotients of
DVRs. Along the way we give a short argument for B\"okstedt periodicity and
generalizations over various other bases. Our strategy also gives a very
efficient way to redo the computations of THH (resp. logarithmic THH) of
complete DVRs originally due to Lindenstrauss-Madsen (resp. Hesselholt-Madsen).
