My personal favorite. This is from some phone texts among a bunch of local randos doing support for a long brevet in the Pacific NW. I'm married to Rando Two, so I can vouch for the truth of this autocorrect event.

Rando One--
Now having Carnegie Masada tacos and beer.

Rando One’s correction--
Okay so that was carne asada tacos mysteriously transformed into Carnegie Masada tacos by my helpful Droid!

Rando Two—
Carnegie Masada tacos must be the kosher version.

Rando Three--
I hear it takes a lot of practice to get to Carnegie Masada!
