Look for the ...

now when you pick a paw paw,
or a prickly pear,
and you prick a wrong paw,
well next time, beware,
dont pick the prickly pear by the paw,
when you pick a pear, try to use the claw,
but you dont need to use the claw,
when you pick a pear of the big paw paw,
Have i givin you a clue?
