Here are some new lyrics, for the more mature set.
The ants go marching:
1 by 1: the last one stops to have some fun
2 by 2: the last one stops and looks at you
3 by 3: the last one screams and tries to flee
4 by 4: the last one cries and begs no more
5 by 5: the last one tries to stay alive
6 by 6: the last one knows he's in a fix
7 by 7: the last one dies and goes to heaven
8 by 8: the last one cries and stays up late
9 by 9: the last one stops and calls you a swine
10 by 10: the last one stops and cries again
