Roger and Tanya Miller are the couple from the Gardening Australia Gooch sketch in Episode 11. Roger and Tanya are interviewed about their flourishing garden in the arid South Australian desert and reveal that their secret is Roger's perineum (or gooch) which has discovered an underground aquifer. It turns out that Roger's perineum is very large and can detect the smallest amount of moisture (including Tanya's own sexual excitement). They blast off in that same sketch.
