Lyric discussion by BigRed97 

I think the "cigar" lyric is another allusion to Pink Floyd ("Have a Cigar"). SW has admitted this song was heavily influenced by the PF "Animals" album, but the song reminds me of music from other Pink Floyd albums as well (the guitar solo in the middle sounds more like it would fit in "The Wall" than Animals to me).

Incredible resemblance to Pink Floyds Dogs from the Animals album. Beautiful song and incredible video. Porcupine Tree are unbelievable!

Compare the beginning notes to Time Flies and Dogs.

Also, part of the solo in Time Flies sounds very similar to Sheep's (Animals) outro.
