""Preposterous matchup, serious response" thread

Just for a bit of fun, I randomly came up with this daft idea for a thread. I was thinking about matchups that are flat out comical due to how bad they are (for one fighter), then taking serious thought to how it would pan out, with as much detail. My idea came when I pictured a near/prime Tyson in with Amir Khan (!); and envisaged he'd be bombed out quicker than Ruiz against Tua. Funny how they're the same height but look at the build difference, Khan could literally not even remotely bother Tyson with his punches, and a Tyson jab would probably take Khan to the morgue. So, thats it, daft I know but we could come up with some funny/strange ones. How do you see Pacman vs Valuev going? MW Hearns vs Razor Ruddock? Go wild!
