Rocky Balboa and Marty McFly were at the Joe Calzaghe-Bernard Hopkins weigh-in yesteday, aka Sylvester Stallone and Michael J Fox.
The pair were introduced onto the stage for a massive contingent of Welsh supporters to cheer them on.
"Rocky, Rocky," they chanted when Sly appeared. And the whole atmosphere was electric. Thousands packed the Planet Hollywood Theatre, roaring on Calzaghe and - jeering Hopkins.
And the coup de grace? Joe walked on stage in a Cardiff City shirt!
Both fighters weighed in at 173lbs, two pounds inside the limit.
Let battle commence.
The Las vegas Strip is primarily about the mammoth hotels that line both sides of it from one end to another.
They are not hotels as we know them in the UK, they are more like little towns under cover. If you weren't that bothered about seeing the rest of Vegas you would never have to leave them.
And more are on the way. Just down from my hotel they are constructing a new place. I don't know what it will be called, but it is an absolute monster.
It makes the Celtic Manor look like a little country guesthouse.
It's like a permanent re-run of the old Barratts advert every time I look out of my hotel bedroom window - it's helicopter after helicopter.
I'm told most of them are either going to, or on their way back from, the Grand Canyon.
Trips to the world famous landmark are all the rage here, with hundreds of street vendors trying to sell you tickets to go.
It's either helicopter or a three hour bus ride. But the chopper ride will cost you a couple of hundred quid.
It's a small world. Rod Woodward, son of former Western Mail football writer Karl, did a stand-up routine at the Planet Hollywood Hotel yesterday afternoon a couple of hours afetr the weigh-in.
Rod went down well, he's got a gift for comedy and could go far.
Just like boxers, comics are entitled to be chuffed at an appearance in Vegas.
