Some pairing names just make you want to spork your eyes out. My personal favorite (er, not-favorite? *g*) is still "Gibozzo" for Gibbs/DiNozzo. (Also, you know you've out of NCIS fandom a long time when you have to google to make sure you spelled DiNozzo's name right...)

There are many horrors out there, but just the fact that "Gibozzo" sounds mostly like "bozo"gets me every time.
