Quotes often heard at the game table, from both movie and TV:
"Why do I feel like we've picked up another pathetic lifeform?" - originally from Phantom Menace (Obi-Wan), now heard whenever the party rescues a prisoner or acquires another NPC.
"Wipe them out. All of them." - Phantom Menace again (Palpatine), now often heard as a party battle-cry.
"We're losing droids, fast!" - Revenge of the Sith originally (Obi-Wan again), often heard when the PCs and-or their summoned allies start to drop.
"I'm going to eat every f-----g chicken in the room." - Game of Thrones originally (Gregor Clegane), a favourite tough-guy warrior quote when starting a battle.
"What I told you was true - from a certain point of view." - Return of the Jedi originally (Obi-wan, yet again!), usually said now by the DM (i.e., me) trying to bail his way out of an error in description or narration.
"I think we're going to need a bigger boat." - Jaws originally (I forget which character), now heard in gleeful tones whenever a party finds a big treasure haul.
"Do pay attention, double-O seven." - James Bond originally (Q), now heard whenever a player zones out for a minute and-or a character fails to notice something blindingly obvious.
