Played for Laughs in two ways: 1. The excessively elaborate secret handshake is noticed by everyone, advertising rather than concealing the secret. 2. The odd ritual is not noticed, to the point where the lack of attention becomes absurd in itself. Note that the Secret Handshake doesn't have to be an actual handshake, but can be any sort of identifying hand gesture. A subtrope of Handshake Substitute.

Montresor affirms that he is in fact a mason. Fortunato reacts with disbelief and asks for a sign. Montresor reaches into his robes and pulls out a trowel, which Fortunado assumes is a joke. Unfortunately for Fortunado, it doesn't occur to him to wonder why Montresor happened to be carrying a trowel around with him.

- Basically any secret society will have a form of greeting for fellow members, or a way of testing to see if a new arrival is one. The Free Masons are the secret society that's best-known and there have been stories about what their Secret Handshake might be. This was because when the Masons were still a society of architects and builders, the members had to travel long distances for jobs and the only way someone at each job site can determine whether you are a qualified architect is to check if you have been taught the secret codes and gestures of the society. It's supposedly a regular handshake, but the ring finger is... wait, who's that at the door? WHAT? NO! NOT YOU! (Troper screams) (disappears)
- According to some ancient accounts, the Christian fish symbol was used for discreet recognition during periods of Roman persecution: one person drew an arc in the dirt, and the other would complete the symbol.
- So why a fish? In Greek, the word for fish is an acronym of "Jesus Christ, God's Son, Savior" (also in Greek, of course; the Greek word for fish isn't "jcgss"). Almost all other acronym stories ... "For Unlawful Carnal Knowledge", "Port Out, Starboard Home", and the like ... were invented well after the fact and indeed after about 1900, but in this case Augustine, who lived around 400 AD ... only about 100 years after the persecution ... wrote about it as if the story were true. The fact that several of the apostles actually were fishermen probably helped.
