Stand-up comedy is a big business of time. From the very first open mic
you will be asked to do 5 mins or less of time. You will have to know that time and not exceed that time or you will not be asked back for another time.
Opening acts are always asked to watch their time especially if there are multiple shows that have to get off on time. MC;'s usually get 10 mins of time, feature acts 25-30 mins of time and headliners are often asked to do 45 mins to 1 hr + of time. In some shows there is a guest spot that may do 5-10 mins of time as well.
