How Bad Can I Be? is a song from the 2012 animated film The Lorax, based on the 1971 Dr. Seuss book. Performed by Ed Helms as the Once-ler, the number explains how he justified cutting down Truffula trees to grow his business while dismissing the environmental damage. The stretched delivery became a popular reaction clip online, shared in edits and memes about greed and self aware wrongdoing. Its clear link to the Once-ler keeps the short excerpt recognisable even when separated from the full musical scene.
