In 2001, Lubach became part of the theatre fellowship Op Sterk Water (with Roel van Velzen and others), with whom he performed at, amongst others, Lowlands, Hard Gelach, Laughing Matters and in theatres in the Netherlands and Belgium. In June 2014, he left Op Sterk Water to present a talkshow.
In 2001, Lubach and Janine Abbring scored a number 3 hit under the pseudonym of Slimme Schemer ft. Tido. This song, Jelle, originated as a joke at the Noorderslag festival; it is a parody of American rapper Eminem and British singer Dido's song Stan. It is about a fan, Jelle, who disappointedly sings (in second person singular) about De Kast singer Syb van der Ploeg, blaming him for not replying to his messages.
