Mount Gay run_Why The Odd glasses?

I was recently given a bottle of Mt, Gay rum (great stuff). It came in a gift box with two glasses. the glasses are oval shaped.
This doesn’t seem to offer any advantage-anybody know why they are shaped this way?

You mean this?

Well, when the running club started running on Mount Gay, they thought it would be funny to wear big old cheesy spectacles.

No, wait, typo…

It focuses the aroma like a brandy snifter.
Is my guess.
