We don't need no stinkin' context!

I was flipping through the James Bond novel You Only Live Twice and came to the chapter where Bond, dressed in all-black ninja clothing, tries to sneak into Dr. Shatterhand’s castle but gets captured and knocked out. As Bond is beaten awake by one of Shatterhand’s henchmen…

Now I realize the moment is tense, but I just can’t think of black cotton ninja underpants without smiling.

Any other book/movie moments that threaten to destroy the mood coming to mind?

‘his ridgid cock’ (or something like that)
(the moment mysterous sci-fi novel turns into trashy sex novel)

Well, in The Passion, at the moment of Christ’s death (and the opening of the Kingdom of Heaven to humanity), it cuts to a scene of Satan in Hell, screaming in anger at being unable to prevent Christ’s assumption of mankind’s sin. The scene really should have been cut for a couple of reasons, but the main one for me was that I as soon as I saw it, I couldn’t help thinking “KHHAAAAANNNN!!!” and almost started giggling.
