Clearing Space on Tivo

Christy has come up with a new rule that Pete needs to delete programs from Tivo to get it less than 100% full before he can set it to record another show. The process goes like this: Pete says "I want to record Spongebob". Then Christy and Pete go through the reasons why we can't delete any of his 47 shows from the hard drive ("I haven't watched the commercials at the end yet", "I've only watched that once", etc.). The process ends with "Dad, can I delete McLaughlin Group?".
