Shane Dundas and David Collins of the Umbilical Brothers are well known for their unbridled imagination and what they refer to as 'structured childishness'. They are currently Australia's most renowned stand-up comedians, touring to great acclaim across the world. Their performances combine mime with ordinary dialogue and vocal sound effects. They use puppetry, slapstick, mimicry and audience participation, and make scant use of props and lighting. After having performed for seven years, their routines are highly scripted. They will perform in English, without translation.
