sri brahmadeva and his fifth face: once a demon named hayagrivasura steal's vedas from sri brahmadeva and to recover these great vedas from the demon sri hari takes avataara of sri hayagrivadeva and kills the demon and thus recovers the vedas from hayagrivasura. all the four vedas would be handed over to sri brahmadeva. after this sri brahmadeva adds one more extra head (this is a drama done by sripati and sri chaturmukha brahmadeva. this is just like a drama in which a person adds some extra clothing during his drama's presentation) to his existing four head to read the chatur vedas. to show the greatness of veda to the world, sri brahmadeva makes one small tiny mistake (this mistake was done intentionally, to show the world the super greatness of vedas) intentionally so that in the future nobody makes such kind of mistake intentionally or unintentionally. sri brahmadeva and sri hari want to show to the world that even a slightest mistake of chanting the vedas can lead to disastrous. thus seeing this sri lakshmi devi gives orders to sri rudradeva to behead the fifth head of the sri brahmadeva which made the mistake while chanting the great vedas. (we should always remember that this is one of the dramas-leelas of sri hari). with this sri rudradeva behead's the sri brahmadeva's fifth head. but again to show the greatness of sri brahmadeva, the beheaded fifth head gets struck (glued) to sri rudradeva's right hand and thus from this time the same head was called as 'kapaala' (a bowl type of thing - the english word cup is the short and corrupted word of the original word kapaala). after sri annapoorneshwari devi (sri paarvati devi) donates some food grains to sri rudradeva and thus the kapaala gets detached from the hand of sri rudhradeva. here it should be noted that this is a pure one of the sri hari's leelas. we should note that who ever makes mistake(s) in any form will be punished by sri krishna. there is no getting away in sri narayana's court.
