A halftime show is a performance given during the brief period between the first and second halves, or the second and third quarters, of a sporting event. Halftime shows are not given for sports with an irregular or indeterminate number of divisions (such as baseball or boxing), or for sports that do not have an extended period of stoppage in play.  Ice hockey games consist of three periods, so there are in effect two halftimes at a hockey game: the first intermission is between the first and second periods, and the second intermission comes between the second and third periods. The intermissions are usually given over to contests involving randomly selected audience members.
