David: If Someone Says...
"No pun intended", then they very likely intended the pun.
This phrase is acceptable in spoken word, but is just stupid when written. If you want someone to notice your clever pun, say "pun intended" instead. Then at least they'll think you're only half an ass-bag.
I'm currently playing Half-Life 2, Episode 2, and am going to be very sad when it is over.
