On 'Journey to the West 2' aired on June 7, Ahn Jae Hyun caused both shock and laughter by referencing sexual behaviors.

During a game called 'Talk with Your Body', Ahn Jae Hyun was tasked with describing a given word with only body language for Eun Ji Won. When the word 'excitement' (which can also mean turned-on in Korean) came up, Ahn Jae Hyun pretended to take his clothes off, made several facial expressions, and even started to loosen his belt.

Based on Ahn Jae Hyun's body language, Eun Ji Won shouted, "Pervert! Sexual desire!" Unfortunately, Eun Ji Won failed to guess the right answer in the given time. 

Fellow cast member Kang Ho Dong, amazed at Ahn Jae Hyun's provocative yet humorous expressions, commented, "You have now completely adjusted to variety shows." Then Ahn Jae Hyun, who seemed to be a bit regretful of his actions, jokingly replied, "Please edit that out."
