From New Kid on the Hallway:

First lines of poems: leave the ones you recognize, replace the ones you don't. Bold new answers. But here's the rub, what do you when you just don't do much English-language poetry:

Had we but world enough, and time,
I never saw a Purple Cow
Byl pozdní večer- první máj - (It was late evening - May first)
Death, be not proud, though some have called thee
Do not go gentle into that good night,
I was angry with my friend
Мой дядя самых честных правил (My uncle of the most honourable principles)
That’s my last Duchess painted on the wall,
Because I could not stop for death
Tiger, tiger, burning bright
