Ethan is a character in the Dad Milk Sketch (see Episode 87). Ethan is a ‘hard working bloke’ who has ‘seen the fruits of his labour’ after struggling on his farm with his wife, Kerbert. In the sketch Ethan tells Terry about his involvement in a conspiracy whereby breast milk actually comes from dads and is then injected into women.
Ethan then gives Terry some Karl Marx literature to read before sucking Terry off, assisted by Kerbert.
