I think the show has done a fairly good job of showing their skills (especially Stan By Me when Mary manages to nearly rescue herself), but it would be great to see Marshall and Mary kick a little more ass now and then. We get to see Mary throw a few folks around, but I can't think of an episode where Marshall really takes anyone on (as he's much slower to anger). Maybe in the new season he'll get a chance to show his dark side (we know he's got one...he's a seether) when hunting down Mary's shooter. He comes off as kinda goofy and relaxed, but Mary once said "don't let the pajama pants fool you...that's one bad-ass lawman" as she's obviously witnessed him in action a few times.
Let them have some fun and work off some aggression once in a while! I'm picturing a bar brawl (can you just see Mary and Marshall throwing people down a bar...they'd have such fun!
I have a feeling Mary could kick Raph's ass if she wanted to, but she'd end up losing to Marshall every time. Mary likes to rank people in the respect file based somewhat on their ability to physically fight with her. Remember in season 2 when Mary and Eleanor are both trying to push her desk at the same time in a battle of wills (can remember the name of the episode but it's the one with the mom and three kids and the oldest son is trying to care for the little ones 'cause his mom is a flake). You can just see Mary and Eleanor assessing each other while they're pushing. Stan looks worried, but Marshall doesn't blink an eye...just gives one his great one liners..."unless you two are going to lather up with baby oil and throw down like real women, we have work to do". But, ultimately, you can see Eleanor go up a notch or two on Mary's respect-o-meter.
