And their daughter, my lovely wife, when she was speaking quickly used to say "obeast" when she meant "obese." We talked about it privately. I'm too smart to correct my wife about something like that in front of others. :-)
Ha...I grew up with a Cuban father, where "Y's" were prounounced as "J's."
"The New Jork Jankees."
There is/was no correcting this. It's still going on to this day.
In geometry class I always said "obese angle" instead of "obtuse angle". Amused the teacher to no end.
