On the December 23 installment of SBS's 'My Ugly Ducklings,' the two singers were seen building Christmas trees with 300 empty bottles of soju at Kim Gun Mo's house.
Kim Jong Min, shocked at the number of bottles, asked, "What are you going to do with these bottles?" Kim Gun Mo explained, "I'm going to make a soju Christmas tree!"
The tree building session quickly became a Christmas tree building competition between the two singers.
