This is what you now are and you can tell them your not just a dj your also a Motivator, Entertainer, Games, Group participation ,silly dance contest - you get everyone dancing silly whoever dances the silliest wins, say things like we looking for the sillest dancer get wild the wildest one wins.(play like a good techno song they know like sandstorm, musical chairs, 2 variations of this.

Get everyone to put there chair on the dance floor, everyone goes around when the music stops everyone sits down, go clockwise, orone boy sits on the chair, the girls go around when music stops girl sits down.

take one or 2 chairs out each time,(tip dont tell the girls till last minute they got to sit on boys they will run away).. other things you can do to liven it up, have them jump like bunnys. rub there tummy and head (you say how was the food), spin around and around, go the other direction, hug each boy as you go round. pat each boy on the head etc.

Another tip always try to let the bar or bat mitzvah girl or boy win, even cheat , they will love you for it.dont let them get out even if they were out,cha cha slide, cupid shuffle,battle of the bands- get into teams of 4 or 5, each team comes up and you play the rock song and they play like there in a band, best band winds by applause usually, (each team can have a name) blow up guitars, sax, mic blow up,
