De Do Do Do, De Da Da Da - The Police

"Poets, priests and poiticians/Have words to thank for their positions"

I'd never actually listened to the lyrics very closely until today, and this line stuck out. Poets, priests and poiticians flows very well. 

She Came in Through the Bathroom Window - The Beatles

"And though she thought I knew the answer/Well I knew but I could not say."

This is one of my favorite Beatles songs and one of the ones I always sing when I play my guitar. I've always especially enjoyed singing this line.
