He's got a good heart

I'm sure we've all heard this expression, but being the equivalent of Ted from How I Met Your Mother (one of the best shows out there, FYI), I always find it funny when colloquial phrases used figuratively also have a literal meaning. I once made a rather inappropriate joke about my friend's brother who has a heart problem (nobody was really offended since it was just my friends, including the brother with this condition, but I did get some awkward glances). I said "Oh Julien's a bad hearted person". I forgot the exact context behind why I said this, but to defend myself from the glaring stares, I said "Guys, he does... he's got a heart condition". Hahaha I know, not very funny... but at the time it seemed like it. Anyways, what I'm trying to say is that what I said was literally COMPLETELY true. Sometimes the phrases in our language just confuse me!
