Frasier, Season 2

[Niles' Freudian slip]

Niles:
If you ask me, Frasier, your trepidation is well-founded. It is possible to move a relationship along too fast, and ultimately marry too hastily. You could find, a few years down the line, that the person isn't really right for you, and then what happens if you meet the right person? Someone who really excites you and makes you feel alive, but you can't act upon it because you're trapped in a stale, albeit comfortable Maris!…Marriage…I have to go now.
