He was caught by police for DUI incident in April 2014 and eventually resigned from any public activity including Infinite Challenge and made the comeback in TV program as a producer for Mnet's hip-hop survival program, Show Me The Money 5, in 2016.

Gil is often called the Unfunny Friend due to his inability to ad-lib as quickly as the other co-hosts.

With his commentaries, Gil has shown that underneath his rugged hip-hop exterior, he is a warm and rather approachable individual.

Consistently offering warm words of encouragement and advice to his disciples to help them ease their anxious hearts, and lightening up the atmosphere with his witty sense of humor, he has become an indispensable personality on the program.

After the DUI incident, he took a hiatus from any public activities including TV appearances and concerts.
