Lol Williams and Nel are just plain idiots. I always specifically enjoy those two being hit around the park, very fun to watch. I remember Williams bowling in the first ODI in the TVS Cup. The Indians hit him all around the park so he had a few words to the batsman. So the Indians decided to hit him around the park some more.
I agree, there's celebration (Akhtar, Pathan, Lee) and then there's stupidity (Nel and Williams)
