One of These Things Is Not Like The Other Lyrics

One of these sounds is not like the others,
One of these sounds doesn't belong.
Can you tell which sound is not like the others
By the time we finish our song.

Did you guess which sound was not like the others?
Did you guess which sound doesn't belong?
If you guessed this sound is not like the others,
Then you're absolutely...right!
