Row, row, row your boat's
(All to be sung in the tune of 'Row, row, row your boat'.)

Walk, Walk, on the Beach

Walk, walk on the beach;
You should see some gulls.
They might defecate on you,
If you steal my sculls.

Walk, Walk, in the Zoo

Walk, walk, in the zoo,
‘till you stand and dream.
If the elephants drench you,
Please enjoy your scream.

Wake, wake every night

Wake, wake every night;
Fall down stairs in pain
Please don’t tell me that you’ve been
Sleepwalking again.
