Collection of scabs

What do you do with your scabs
when you pick them from your skin
flick them at annoying girls
or stick them in the bin

Or perhaps you store them in a jar
to compare with your best mate
who'll claim he had far more
that your little jar of eight

Or maybe you just sprinkle them
over your sister's beans
trying to repulse her
by any way or means

But whatever you do with them
never must you fear
as long as you have cuts and scraps
your scabs will heal you clear
