Put your birthday cake with its lit candles in front of your amp, plug in one of your Bongos, turn that amp up to 11, make a wish for yet another Bongo, and blow that cake with its now very extinguished candles clear across the room. Make sure that your other Bongos are not on guitar stands in the line of fire of the projectile birthday cake or you'll have quite a mess to deal with which I'm sure will cause you to start some kind of "help with mess" thread.
