I picked the "Western Michigan Bulldogs," even though I was unaware of the mascot change. ;-). Maybe having a bronco as a mascot name was a little too violent for this PC Era!
This may be the reason! PC Police show up often.
I just heard on the radio that it is distasteful to say things like:
"He/she brings home the bacon" or "kill two birds with one stone" instead you should say:
"He/she brings home the BAGELS" or "FEED two birds with one SCONE"
You cannot make stuff up like this--it is a wild world we live in.
