Never ending WHY?

(Above qns ask by my toddler son!)

Sometimes i wish to lie to him to shut his qns up! But i know it is wrong to lie to him. I try answer him, but he will repeat the SAME qns again & again! Arrrhhh! Till he got another qns to ask me! I try ignore his qns, but again I felt I shouldn't ignore him. It's like I'm not responding & interacting with him. Sort of consider rude. Still, he will ask again & again...

How should i endure & react to his never-ending WHYs???

WHY MUST HE ASK WHY???
