The TV chef and Piper are two of the celebrities taking part in Channel 4's week-long project, which involves the stars taking on unemployed civilians and training them in hospitality skills and trying to find them work.
Yesterday, Ramsay, who is running the Hotel GB kitchen, visited Piper in the hotel spa and ended up getting a hands-on explanation of how male genital grooming works.
Ramsay was shown the differences between "a small landing strip" and "a Brazilian" that male customers can select from.
A naive Ramsay was given a diagram of the different patterns available for men who want some "modern grooming". Piper then made the Scotsman bend over and get on fours and revealed thee best practice for tidying up a man's nether regions.
Hotel GB starts tonight (October 1) at 9pm on Channel 4.
