On October 17, tvN aired the first episode of 'Three Meals a Day,' featuring Taecyeon and Lee Seo Jin where the two were thrown into a countryside house and given the mission of eating three meals a day. 

Three meals a day sounds easy on the surface, however, there was a catch. The challenge was that the only ingredient that the producers themselves would provide was rice and the cast members had to prepare their side dishes with the ingredients they found around the house. The menu will be then chosen by the producers.

Another condition was that in order to live a fully organic and an analogue lifestyle, the producers took away their cell phones for the duration of the filming. However, they were allowed to use the provided landline phone.

While using the landline phone and without his mother's contact information stored on the cell phone, Taecyeon realized that he didn't know his mother's number and had to go on a wild goose chase trying to find the number. He first called 114 (similar to 411 information directory) and asked for JYPE's office number. When he called the office, he received a busy message stating that they could not reach the phone at this time. 

The idol then muttered disappointingly, "They're not answering..But I don't know my mom's number..."
