Kisses Sweeter Than Wine - S3-E5
[Martin sees Frasier has a lot of cuts on his face from shaving.]
Martin: I thought you were just going to slit your wrists. Looks like you went for death by a thousand cuts.
Frasier: I cut myself shaving because I was shaving without water. Why was there no water? Because I had to move your chair, which gouged the floor, which made me call for Joe, who found bad pipes, which called for Cecil, who ate the cat that killed the rat that LIVED IN THE HOUSE THAT FRASIER BUILT!
Answer: It equals the record of James Arness of "Gunsmoke" for the actor who's played the same part on TV NOT in a soap opera. If you include soaps there are two main contenders - William Roache, who's been playing Ken Barlow in "Coronation Street" in the UK since 1960. Don Hastings has been playing Robert Hughes in US soap "As the World Turns" since 1960 as well.
