Somebody's brain must have taken a nap when Lipscomb was brainstorming for nicknames. For those who didn't realize their flaw, bison is the same for both the singular and plural forms. Lipscomb, however, decided to defy the laws of language and add a "s" to "bison."
Sam Houston State Bearkats
The only reason Sam Houston State is here is because I hope that they spelled "Bearkats" with a "k" to be original and different.
Miami Hurricanes (This is more for the mascot than the nickname.)
I did some research on a question that so many college sports fans think about; If Miami's nickname is the Hurricanes, why is their mascot a duck? The answer is that it is not actually a duck, but a pelican. It is their mascot because during a hurricane, a pelican got carried, beak first, into the school's flag.
The bird died while hanging from the flag by its beak. Rather than give the bird a normal burial, they decided to honor it by turning the dead bird into their mascot. I hope that this answered a question that many other NCAA fans have had over the past years.
One more fun fact: On the subject of mascots, William & Mary once thought about making their mascot asparagus.
