Husband and wife agreed tht whenever they wanted to have SEX, they will call it 'PHONE CALL' so tht the children would not understand. One day Dad sents son to tell Mum tht he wants to make 'PHONE CALL'. Mum replies, tel yr dad tht network is busy today. Dad replies, tell yr mum tht the call is urgent, if network is busy, then am going to a Public Phone Booth. Mum replies; tell him tht if he dare goes to a Public Phone Booth, i will OPEN a business centre and all 'PHONE CALLS' will be free[emoji23] [emoji23] [emoji23] [emoji23] [emoji23]
