Great to Be a Baby

 is a song featured in "Agent Doof" while Phineas and Ferb are babies.

Lyrics

 * I can crawl around on the ground
 * I'm allowed to make obnoxious sounds
 * I can be asleep both night or day
 * I ain't got much hair to brush
 * And there ain't no need for me to flush
 * And that is why you'll always hear me say
 * Man, it sure is great to be a baby
 * You can sit all day and suck your thumb
 * I can chew my brother's toes
 * And play with the stuff inside my nose
 * And the pans in the kitchen cupboard make great drums
 * (Musical Interlude)
 * Get strolled, carried, burped and cuddled
 * Wiped, powdered, diapered, swaddled
 * Hugged, tickled, dried, tossed
 * Ported, dressed, kissed, washed
 * Swung, spoiled, peek-a-boo!
 * Pampered, nibbled, coochee-coo!
 * Snuggled, cuddled, rocked and fed
 * Sung to, nursed and put to bed

Continuity

 * Babies from earlier episodes are seen during the song.
