Euugh!

How about something to the tune of Bare Footin' on the lines of Nit pickin'

Itchy Coo head?

Nit picking away, nit picking awayay,
You know the longer they are at playschool,
The more you're nit picking away...... (sorry Paul Simon....)

Oh Susannah, Oh put that comb away,
Your brother has the cooties,
So we shave your head today!

Sorry...

So far not been bothered by them, can only be a matter of time. For those who prefer a more 'herbal' remedy, tea tree oil on the comb helps.
