In The Beatles' White Album song "I'm So Tired", one of the verses has the following lyrics:
I'm so tired, I'm feeling so upset
Although I'm so tired, I'll have another cigarette
And curse Sir Walter Raleigh
He was such a stupid git
My question is, why was Sir Walter Raleigh "a stupid git"? I only know him as a poet, so I'm assuming this is some kind of reference to one of his works?
