"3rd Rock from the Show" is a very funny comedy series about a group of aliens disguised as humans. John Lithgow (one of the most underrated actors of all-time) is fabulous as Dick, the confused and overly dramatic alien posing as a college professor (I think - it's been so long since I've seen this on TV!). Sally (Kristen Johnson), Tommy (Joseph Gordon-Levitt) and Harry (French Stewart) all join in on the fun as his clueless, bumbling pals - Tommy is an old alien in a teenager's body, Sally is a male in a female's body (or so we are led to believe). Harry is a walking radio who receives incoming transmissions from their home planet.
It may sound silly but that's the entire point! It has some very funny quotes like, "Last week I didn't even know the difference between Bill Pullman and Bill Paxton!" Dick: "Pullman is the fat one." "I know that now!" (or something like that). A lot of it has to do with pop culture and as a result you may have to be American to "get" some of the jokes.
One of the top ten greatest television shows of all time. Miserably underrated. It gained a strong cult following while on TV and was awarded with many Emmy nominations but never really become as successful or popular as "Seinfeld," etc. Too bad.
