Big clocks go tick-tock, tick-tock (slow tick-tock), little clocks go tick-tock, tick-tock (somewhat faster tick-tock), and little pocket watches go tick-tock, tick-tock (very fast tick-tock). And cuckoo clocks go cuckoo cuckoo (bounce the child on your knees), and the church bells go ding-dong, ding-dong (slow, long back and forth), and the alarm clock goes ... rrrrrrrrring (tickle child)
