ROT13 Sentences Challenge

The neuron in my brain that is responsible for me knowing that people get tattoos of “Chinese” characters bumped into the neuron in my brain that is responsible for me knowing that ROT13 is used as a simple obfuscation cipher, leading to the idea of:

“What does my tattoo mean? Oh, it is ROT13; it says ‘HOPE’.”

The neuron in my brain for “funny” only half-fired, so the three hundred million neurons responsible for me being a nerd thought “Ooh! A problem! Let’s solve it with Python!”

So, the challenge was: What sentence becomes another valid sentence when ROT13ed?

First, I went through a wordlist (267k words) looking for ROT13 pairs. They are listed at the bottom.

Then I went through and filtered out the useless ones. ERF and RES are words?

Here is the filtered list:

EBB=ROO
GEL=TRY
ENG=RAT
ANNA=NAAN
EBBS=ROOF
BIN=OVA
ANT=NAG
HE=UR
BO=OB
ENUF=RAHS
GREEN=TERRA
ANA=NAN
ENVY=RAIL
CHER=PURE
GURL=THEY
AHA=NUN
FUR=SHE
ABBA=NOON
AVO=NIB
BAR=ONE
BE=OR
BA=ON
ERRS=REEF
CEL=PRY
CHA=PUN
FUBAR=SHONE
BUB=OHO
BARF=ONES
BAL=ONY
IRK=VEX
ART=NEG
ARC=NEP

Then, I chuckled at some randomness.

  • TERRA maps to GREEN.
  • BOOBBOOBBOOB and BALONYBALONYBALONY pretty much come out unscathed by ROT13.
  • CHER is PURE (or the opposite, depending on your perspective).

But remember the challenge? Are there any sentences that only use these words?

Well…

AHA! THEY SHONE GREEN GEL ON ONE’S ROOF.
NUN GIRL, FUBAR TERRA! TRY BA-BARF EBBS.

So, no, not really. None that I found. Perhaps if you were willing to break up word boundaries differently? Can you see any?

  1. That IRK = VEX makes me ridiculously happy.

    REFF = ERRS seems politically appropriate, but a bit too late.

  2. er, REEF = ERRS but you knew that already.

    P.S. Tod say it isn’t possible. Not enough verbs conjugated to fit the nouns available.
