Girls' Generation's Taeyeon has been flagged as the member with the lowest stamina.

To celebrate Children's Day, the May 5th episode of KBS's 'Invincible Youth 2' held a 'Children's Sports Day' special, playing numerous games in order to win against the opposite team.

The two special guests, Brown Eyed Girls' Narsha and Taeyeon went up against each other in an obstacle race as they bent down and covered their knees with their long-sleeved t-shirt. While circling the course in a rabbit pace, the two had to cleave their way through numerous obstacles, jumping over cushions and climbing up stairs.

Proving that age is just a number, Narsha showed off her athletic ability as she quickly made her way through obstacles, leaving Taeyeon far behind. MC Kim Shin Young hilariously remarked, "Did Narsha unnie take some pills?"

Upon seeing Taeyeon having difficulty in overcoming the barriers, Narsha was prompted to wait from time to time and even stop before the finish line. Taeyeon did her best to chase after the 'adult-dol' however, Narsha won the round, giving her team a taste of another round of victory.

Check out the hilarious cut below!
