Okay, I had another one from a few years back that some may not have
heard, so will have to share it as well.  

Four years ago we flew from Corona (AJO) to Cobb County, GA in 6.1 hours
with one fuel stop in Pampa, Texas.  We fly at 65 percent power with
GAMI injectors, lean of peak.

We were caught up in the best jet stream of over 100 knots.  We were
showing 369 Knots ground speed!!!  ATC came on and asked what kind of
jet we were. Response:  We are not a jet.  
ATC:  What kind of twin are you?  
Response:  We are not a twin.  This is a single engine.  
ATC:  Are you sure?
Response:  We were when we left.
ATC:  Well, you are overtaking a Lear so I have to vector you.

Okay, so we were in a slight descent, but that is still pretty darn
good!

After the vector, ATC came back on and wanted to know what we were
flying.  We informed him it was just a little experimental plane built
in the garage!  That sure is fun to say!  Fly safe!

others!)
