do not know if this constitutes as a joke or not, but many of my foreign friends are amazed at the number of chat programmes available in India, though none of them have been able to downoad a single on of them via the net.. a few of the chat softwares are `alu-chat', `papri-chat', `dahi-chat' etc. etc. (sorry, but if you do not know the Indian language, this one will probably confuse you)
