Translate "Friends" Chandler's line "Dude, look at the room"

Season 1 episode 23 I went to see it myself. Chandler told a joke, Rachel told another joke, and then Chandler said, dude, the study room told a joke to prove that humor is subtle, depending on the occasion. Then he said, you know what I mean?

Another time Chandler asked Joey to water Monica's flowers together, and then he said, "You know what I mean", and then Joey said to pee on the flowers together. Everyone knows how to water flowers. Monica called the first time offering flowers. .

Chandler is my favorite ~ but I only like the first four seasons ~ I don't like Monica and Chandler together ~
