It's often seen/ often used... it only appears in 2 episodes, so how does the word often apply?? --Sigmund 2014 (talk) 02:03, January 16, 2015 (UTC)
- OK, I guess it's what you might call the "playing along" angle. Let's pretend that what we see in the episodes, movies, etc. is only a small fraction of what IR really does. Well, if you ask me, it's dumb. --Sigmund 2014 (talk) 01:44, August 1, 2016 (UTC)
