I will present some recent results for the dynamics of the filament formed during the drop pinch-off process: 1) a new family of exact solutions to the Upper Convected Maxwell model for a purely extensional cylindrical filament, and 2) observations of the unusual pinch-off dynamics of a wormlike micellar solution, in which the filament instability is highly localized.
