Over The Top. Normally in the sense of too much to be real, as opposed to Blackadder Goes Forth.
OTT was the adult version of Tiswas, Over The Top lasted one series. It didn't live up to expectations because Sally James refused to get naked or even do the show. The producers didn't push the envelope and make it well OTT so missing the chance to shock the nation (which we all hoped for).
Not to be confused with OTT, Lucien Victor, a real French hero and mentor of The_Baron_of_Castleshort.
