What we're watching: Yup...summer is pretty much here. The AC is on and repeats are playing. On NBC the repeat of Will & Grace's series finale is on, followed by previously-shown episodes of Earl and The Office. NBA Playoffs action continues with Game 2 of Pistons vs. Heat, with the Pistons facing a must win at home after dropping Game 1 (Go Pistons). Otherwise you can check out the Charlies Angels sequel on ABC, but don't forget to check out an encore presentation of the satellite launch Clint pointed out on HDNet.
