Whose line is it anyway? is a comedy show in which participants are given a theme and they are supposed to come up with an act according to the theme given to them.
According to Oxford Dictionary, one possible meaning of anyway is to ask a question, like
What are you doing here anyway?
but I am not able figure out the meaning of anyway in this expression. Maybe it is because I am not able to imagine the context it has been said in.
What is the explanation?
