"So I said to the gym instructor: 'Can you teach me to do the splits?' He said: 'How flexible are you?' I said: I can't make Tuesdays.'"

The quote by Tim Vine is a funny take on the common exchange in between a health club trainer and a trainee. The trainee is asking the instructor to teach them how to do the splits, and the trainer is asking the trainee how versatile they are. The trainee's action is a humorous one, as they respond that they can't make Tuesdays, suggesting that they are not very flexible. This humorous exchange highlights the value of versatility in order to do the splits, and also the importance of having the ability to dedicate to a routine schedule in order to find out the skill. The quote is a lighthearted way of showing that versatility and dedication are both essential in order to learn a brand-new ability.
