Come "Father's Day", the litter bug's gonna getcha;
Rowlf: The urge is righteous, but the face is wrong.
Both: I hope that somethin' better comes along.
Kermit: Still, it's fun when they're fetching,
And agree to see an etching
That you keep at your lily pad.
There is no solution, it's part of evolution,
Rowlf: The pitter-patter of soles,
The little feet of tadpoles!
Kermit: (spoken) Ah, Rowlf, tadpoles don't have feet!
Rowlf: (spoken) Oh. Sorry about that.... 2, 3, 4!
