"School Football Team" joke

DURING the selections for the school football team, the coach gave the players the option of selecting their own playing positions. The players made up their minds and the coach began to ask them about their playing positions. The conversation went as follows:
Coach:' Banerjee?'
Banerjee:' Centre forward, Sir.'
Coach:' Kumar?'
Kumar:' Right back, Sir.'
Coach:' What about you, Singh?'
Singh:' There is a slight problem.'
Coach:' What?'
Singh:' My friends are wicked, they want me to play Left out, Sir.'
Coach:' So, what's the problem?'
Singh:' How can I play Left out? Won't I have to play outside the field, Sir?'
