Lyric discussion by Bobo192 

PPM was one of those tracks which sounded innocent, but had a deep subtext. More of that anon.

The chorus was suggested by Bing Crosby's 1932 song "Please", written by Robin/Rainger, which starts off by investigating the relationship between the homophones "please" and "pleas" - "oh please, lend your little ear to my pleas | Send a ray of cheer to my pleas | Tell me that you love me too".

Some, most notably Robert Christgau, music editor of New York's Village Voice, have suggested that this is an explicit allusion to oral sex.

Suddenly, I'm never going to view this song in the same light ever again...

@Bobo192 Of course it is about a blowjob! John Lennon was always very raunchy and, after all, he was 22 years old whe he wrote it.
