Dumps has attended quite a few Please-Spare-Daddy-The-Agony birthday parties recently. Considers himself a Pro.
Dumps also likes cake. A Lot! Really. Seriously.

So, when he is in a room with lit candles, he extrapolates, and hunts for that cake. If he finds one, he will run around shouting ‘moon – desparately searching for that spoon to dig in. This is with no regard to where we are in the birthday-celebration timeline.

But being the gentleman that he is, he sings the first few bars of Happy Birthday before creating the ruckus.
If he is feeling overly generous, he will throw in a few bars of “A B C D …” as well.
And then promptly clap – signalling the end of all the rituals, and suggesting that we need to cut the cake.

Heaven help you if the birthday kid has not made his or her wishes yet.
