The only storyline I remember of season 9 is the girls discovering their WIKIFEET entries and deciding to sell their feet pics to raise money for Raquel's nose job. It beggers belief that this was a real 'storyline' and not a 30 rock Jenna bit :D
I think you can just skip season 9. I don't remember anything notable happening.
Actually everything between this and the beginning of season 10 can be skipped
Who knew Elton could be such a SUB, I thought he was going to end the comment with "Please master fill my water bowl before you generously allow me to lick your boots"
