Mike Tyson is gearing up for his big Thanksgiving weekend fight -- BY EATING ROY JONES JR'S HEAD!!!
Sure, it's a cake "head" -- but Mike went straight for his favorite part, THE EAR ... and the video is hilarious!!!
The 54-year-old fighter got his own adorable kids to take part in some Turkey Day trash talk directed at Roy -- warning the fighter to watch his lobes, or he'll get the Evander Holyfield treatment when they clash on Saturday night!
In the clip, Mike starts off by acknowledging he has a lot to be thankful for this year -- like the reported $10 mil he's scheduled to make from the Roy Jones Jr.
