Curtain Razor is a 1949 Warner Bros. Looney Tunes short directed by Friz Freleng.

[2] An operatic tenor voice and piano music for the Act III Prelude from Richard Wagner's opera Lohengrin accompany the opening credits and earth-shaking scene as hopeful stage talents wait outside the office of Goode and Korny: Talent Agents.

The voice turns out to belong to a tiny grasshopper, who ends his performance with Blanc's trademark pronunciation of "Cuc-amonga".

He dons a devil's costume and swallows atomic powder, TNT, Gasoline, and finally, a lit match, which he explodes into total nothingness.

Curtain Razor is available restored on the Looney Tunes Super Stars' Porky & Friends: Hilarious Ham DVD release and the Warner Archive Collection Blu-ray release of Cats Don't Dance.
