30th

There are explicit things Liz must do when celebrating her 30th birthday. First, watch the When They All Turn Thirty episode of Friends from season 4. Second, listen to the thirtieth podcast of Ouch from the BBC from August 2008...it's the one where they make fun of soap operas popularity with those who have learning disabilities. And third, wait for a present from the Birthday Blog Fairy. She gives gifts to those who live in apt #6.
