Song Title?

[711]

Anyone know the title of a little ditty we used to sing in primary school in the `50`s? The words go something like :- "What a silly thing to do, when a gnat flies at you, to let him on your arm alight and then expect him not to bite". Any help appreciated.

[Calibax]

Found this but don't know what it's called or who it's by.

What a silly thing to do
When a gnat flies at you
to let him on your arm alight
and then expect him not to bite.

How was I to know I pray
just what pranks gnats can play
for on my arm he danced a jig
and now it's swollen twice as big
