I like "Birthday" and "Martha, my Dear" the most from the White Album. I like the piano parts in "Martha." I've always liked John's "I'm so tired." Whenever I hear it, I will compulsively sing it over and over for at least 2 to 3 days, being completely unable to stop.
I had a girlfriend at the time who hated "Birthday." She thought it was stupid and didn't make any sense. Well, we broke up later and not because of the song. I needed to find a girlfriend who liked all the Beatles songs I liked but I never did! This is why I've been single all my life.
