Hitting the wrong code on the turbolift controls will take you on a whirlwind tour of what Q thinks is fun. Like the party deck on deck eleven. Complete with pretty girls in little bikinis and fruity drinks with umbrellas!
Q: Why? Because I can! Nya ha ha ha ha ha hah!
Kicking Q in the "unmentionables". What else can you say?
Though punching him in the nose is funny too.
Q's reaction to Biraka's smooch on the head.
Q: He kissed me!
Some of Q's reactions to you/Qaylan using your tricorder on the Borg who tried to take over the bridge instead of killing it, thus getting yourself and the crew killed.
"Excuse me, am I mistaken? But isn't there a Borg on the bridge trying to control the ship! What are you going to do (hits you on head with the tricorder) Scan it to death!?"
After Q brings Quint back.
Quint:Where am I? What's going on? Wait...I don't think I want to know.
