I vaguely remember hearing something about Mike the Tiger, but I couldn't tell you when he died, or whether I heard about it at the time or whether I confused news of sickness with news of death or vice versa. It doesn't register with me as very important. I could have heard about it, forgotten about it, and heard about it again as if for the first time. I do not think I have heard any physical person I have encountered in daily life mention it one single time. But I could be wrong, and forgotten that too.
Mascots die, and are replaced with other mascots. I couldn't tell you what version of Uga they are on now.
