Weight Watchers lament

Hello, do you know me?
well if you don't you should
I'm half a pound of lovely fat
who'd stay here if I could

No-one wants to lose me
so i'll just hang around
If lost, i'll hear you moan and say
"it's only half a pound"

You think I'm not worth losing
and wonder why you came
but keep on moaning every week
and they all will think the same

Then with you I'll gladly stay
I'll stick to you like glue
around your Leg's, your chin and hips
and other parts of you

My fellow halves will come along
and join up for a laugh
so the moral of my tale is this
be grateful for each half!!
