I've had this happen before, where some tool or technology sounds like another tool. Combine that with people with varying accents, and you can quickly devolve into frustrating conversations.

"Okay, so the Foo system is having problems. Mary said they tested it using some cat scripts. Can we get Mary to share those, as we're unable to reproduce it"

(some time later)

"Oh, so Mary was using Katt with a K and not cat with a C."
