The largest Lion right now is Aaron Gibson, #71, he plays OT, and he is 6’4" at a whopping 380 lbs.
The largest Bear currently is James O. Williams, also #71, playing OT. He is a 6’7", but a mere 331 lbs.
So the Bear has the reach, but the Lion is carrying a bit more heft. Hard to say. I would probably give the edge to the Bear but I suppose it would depend on how hungry they were.
I have to side with Ura-Maru on this one. Any self-respecting Lion would send the lionesses in against the bear, and wait around to get the soft bits. No bear, no matter how hungry, how horribly bestowed with teeth and claws, or what position he plays, is going to come out ahead against a bunch of organized women. And even if he does, there is a pack of hyenas skulking around waiting to jump him anyway.
What list? And will I like this list?
The lion aside, for now, I’m not inclined to think you’re going to inflict much damage on me:) Unless, of course, you threw the [Stanley Cup[/ur] at me!
The emotional damage I already have, you’d have to dredge something up and keep on dredging to get me much worse than I already am. Nice thought, though. Plus you don’t know what to dredge up.
It’ll take a fair amount of taunting . . . how do you respond to someone smiling as you taunt? And, again the lion aside, unless you’re a VERY fast runner you aren’t going to outrun me.

You slightly resemble Nikki Cox, facially and hairly, in that pic. Rest of you’s nothing like her, but from the neck up . . .

Now, for the part of this post we might all care about:
[ur]=“http://www.britannica.com/bcom/eb/article/3/0,5716,49573+1+48425,00.html”]Average Lion size:](http://geocities.com/sdpeoplepages/bio-brat.html) A full-grown male is about 1.8-2.1 m (6-7 feet) long, excluding the 1-metre (3-foot) long tail; stands about 1.2 m (4 feet) high at the shoulder; and weighs 170-230 kg (370-500 pounds).
Polar Bear size: Adult males grow eight to almost nine feet long, and weigh 800 to 1,400 pounds,On two legs, a large male polar bear may stand ten feet or, rarely, taller.
An important point to bring up is the prey they hunt. Lions don’t usually have cause to kill animals heavier than, say, 200 lbs. Polar Bears have been known to attack and sometimes kill beluga whales, which can reach 15 feet long and 3,300 lbs. Don’t know if several bears attack at once or one just smacks it hard or what. Lions, however, hunt in packs.
So my vote: neither. They’d tire eachother out to the point where it’d be whoever died second who won.
And what have we learned from this exercise, boys and girls? PREVIEW YOUR VB CODE!
Surely the Romans did this experiment at some point. Is there no record in the annals of Western History?
Pliny the Younger made reference to it in his second letter, the first covering the death of his father Pliny the Elder in a volcano eruption. I regret to say I do not remember the recipient of the letter, but it was written for an encyclopedia of sorts, which (the encyclopedia) of course is lost to history.
Are lions broken?
Who do lions mate with? 
No, but they’re frequently broke, due to a poor work ethic and lack of proper education.
Lioneses, mostly. Occasionally tigers, in captivity. Possibly a girl I knew in college, but I’m reasonably sure she was speaking metaphorically. At least I hope so.
Bad deal for them, really. They support the males, get second dibs on the food, and they don’t even enjoy sex. Which, assuming they’re to be trusted, makes them pretty much interchangeable with most comidiannes.
To clarify, I’m not refering to First, Second, or Third mates who happen to be lions, who of couse must be responsable to even be considered for thier posts.

I’m going for the bear. And when you say bear, you mean polar bear, right?
