We used to stand at the front holding a fake cake with candles* while everyone sang "Happy Birthday to you . . . " and you would then rattle off the list of presents you had.
Great fun unless your Dad is on 6 'til 2 and you want to wait until after school to open your presents when he's home. I stood there and rattled off a completely fictional list of stuff I had, feeling more & more self aware with each item.
* Yes that's right real candles. I had no eye protection, fire proof overalls in a suitable Hi-Viz colour (yellow is very "in" this year) with fire & rescue teams on standby.
