Jessica and Krystal recall a time they were drunk + divulge their thoughts on the last episode of their show

On the July 29 edition of 'Jessica & Krystal,' the two pretty sisters discussed a time when they got drunk.

The two were asked whether they had gone to get a massage together before.  Krystal said, "There was a time we went, last winter.  At the time, she and I drank wine and got drunk."

Jessica revealed, "That was the time when Chun Song Yi [played by Jun Ji Hyun] from 'You Who Came From The Stars' was popular.  The both of us greeted people like her while intoxicated."

Krystal added, "We said 'Boong Boong ah~' to every car we passed," as Chun Song Yi called her own car by that name in the drama.

Also in this episode, the sisters revealed their thought on the last day of filming their reality program together.  Jessica said, "I'm sad.  This was our first time [filming together], and I think it let us spend time together.  We got to do a lot of stuff we wouldn't have been able to do even if we paid for it.  It was stuff that would've been impossible had the staff not done it all for us.  This was the most memorable.  They were good memories for us."

Krystal said, "I think it's really nice that there is something my sister and I could watch when we're both grandmas.  I could show it to my daughter later on, saying, 'This is your mom and your aunt,' and I can laugh as I watch."

The 10-episode reality program will finish on August 5.  Meanwhile, you can enjoy a random but cute clip below!
