''Like, all of the above, yo,'' responds Allen, still in character, and his impression is so good it's easy to imagine actor Aaron Paul (who played Pinkman on the show), on the other end of the phone.

Pinkman is not the only Breaking Bad character in Allen's repertoire. He also does a solid impersonation of Walt White, and an even better one of Walt junior, White's son, who has cerebral palsy.

This week Allen will make his international debut at the Melbourne International Comedy Festival with One Man Breaking Bad. In it, he imitates everyone on the show from White's wife, Skyler, to his crooked lawyer, Saul Goodman, condensing the show's six seasons into a 60-minute performance.

It was born out of a YouTube clip that Allen posted last September, in which he posed as a homeless man doing Breaking Bad impressions for food. The clip went viral and Allen saw that the public appetite for Breaking Bad, which concluded last September, was still huge.

''I realised that there was still this huge hole in Breaking Bad fans' hearts - and in mine - when the show had ended,'' says Allen. ''We're like addicted to it, as Jesse and Walt's customers were to their meth, and so the natural progression for me was … packaging it as this huge fanboy love letter for the fans.''
