I want Fridays off!

If it’s Friday, Letterman must be off
It’s official: David Letterman is adopting a four-day work week for the month of June.
The CBS “Late Show” host announced late yesterday that guest hosts would be sitting in for him on Fridays for the remainder of the month, starting tonight with baggy-pants comic Tom Green. he other hosts will be Kelsey Grammer June 20 and Jimmy Fallon of “Saturday Night Live” on June 27. Tom Arnold subbed for Dave last Friday.
Letterman raised eyebrows last week when he made the surprise announcement that Arnold would sub for him on Friday. Letterman also disclosed then that he was thinking about taking Fridays off this summer.
