In the TV-show Friends there's the following scene in Season 3 Episode 23:
[Scene: Pete's apartment, Monica showing the gang around.]
Monica: Okay, this is the den.
Chandler: (sitting down on the couch) I-kea! This is comfortable.
It is obvious that he relates Ikea company to the situation.
My question here, when sat there he first said "I" then completed it with "kea" as if "I" indicates an exclamation of extreme comfort. What is he indicating?
