Let me tell you a thing about embarrassment.
Embarrassment is not, for example, simply farting. Embarrassment is farting in front of your entire fifth-grade class on movie day when the lights are out and everyone is silent.
...That, uh, happened to a friend of mine.
What makes something like that so funny, is not that it happened, but that it happened when someone was there to witness it.
The same can be said, then, of the most embarrassing MLB photos of all time. It's not necessarily that they were embarrassing moments in themselves, but it's that someone was there to take a picture of it when it happened.
And for that, we most thoroughly thank them.
Submitted for your amusement are the most embarrassing MLB photos ever!
