You know the ear that Vader famously ripped off of Mick Foley's head in a wrestling match 25 years ago??
Yeah, Foley just showed it to TMZ Sports -- and it's still not fully repaired ... AND IT'S STILL GROSS AS HELL!!!

We spoke with the wrestling legend out in NYC earlier this week and asked him for a little injury story time ... and that's when he retold us the famous tale of him losing a piece of his ear in 1994.
