Anil Kumble's latest Sobriquet: AK37

While driving to work this morning, I noticed a used car dealership hoarding on Chamiers Road -Cenotaph Road crossing. It read:

India's Latest Weapon - AK37

Capt. Anil Kumble Age 37 - AK37

Wonder what the cool Capt. of Indian cricket team has to say on his latest sobriquet!
