Shane Dundas (born March 30, 1971) and David Collins (born January 19, 1969) known as The Umbilical Brothers are an Australian comic duo.


Dundas and Collins met in 1988 at the University of Western Sydney in a salsa club on a hot summer's western Sydney's evening, where Collins swung around and broke Dundas' nose. Although their instuctors tried to keep them apart after the incident, they got together on their own, made amends and began writing routines.
