Forum:Splinter Cell: Chaos Theory Reference

It says in Gordon Freeman's page that Splinter Cell references Gordon and his crowbar. It says...

"In Splinter Cell: Chaos Theory, Anna Grimsdóttír remarks to protagonist Sam Fisher that 'crowbars are for geeky video-game characters', poking fun at the fact that Gordon Freeman is a scientist by profession."

When and where does this happen? I've played through several times and not heard this line.
