Homer’s not a very talented guy. He’s rather dim-witted, has a dead-end job and is entirely unathletic.
But every now and then, he’ll turn out to be very good at something. For instance, he’s a great golfer (as his playing at the country club proves) and, according to Marge, he’s more than satisfactory between the sheets (“Yeah, but none of my friends can watch me”).
Apart from golf and snuggling, can we think of anything else Homer is genuinely skilled at?
He’s been shown to be fairly talented at baseball, at least where batting is concerned. He is also remarkably capable of surviving a wide variety of personal injuries.
He’s a good singer and won a Grammy Award.
He has a certain perverse resourcefulness, even though it’s usually not tempered by wisdom. Also, he’s a man who isn’t afraid to follow his dreams, no matter what they may be that particular week.
Eating potato chips. Ordinarily, not a particularly useful skill, unless you happen to be on the Space Shuttle and something goes horribly, horribly wrong 
He almost became world heavyweight boxing champion.
That’s right, because he can take a punch in the head really well.
Also, he can catch a cannon ball with his belly.
Homer is good at bowling. He once bowled a perfect 300. He’s apparently not as good as Richard Nixon who, according to a plaque, bowled back to back perfect games (yeah right).
Homer is good at taking physical abuse. Two by fours to the head and cannon balls to the stomach are just a few things that come to mind.
“Homer, Homer Simpson, he’s the greatest guy in history. From the town of Springfield, he’s about to hit a chestnut tree…”
Legndary fisherman, he is the only guy to have caught “General Sherman.”
Beverage inventor: “The Flaming Ho…” “Moe.”
Model for an award winning painting.
Successful bootlegger.
Discoverer and first manager of Lurleen Lumpkin.
Minor league baseball mascot.
Night school instructor. (Secrets of a successful marriage.)
You forgot to mention that one doesn’t have anything to do with other.
He is also extraordinary good at avoiding temptation, having had the chance to boink both Lureen & Mandy, but turning them down. While he did knock up Marge before marriage, he is a faithful husband.

Seems to be well versed on Supreme Court Justices.
“Warren Burger…mmmm…burger.”
Marge: Do you want your son to become become Chief Justice of the Supreme Court, or a sleazy male stripper?
Homer: Can’t he be both, like the late Earl Warren?
Marge: Earl Warren wasn’t a stripper!
Homer: Now who’s being naive?
He also invented plenty of other stuff such as the 6-legged chair, the automatic hammer, the lazy-bowl, the everything’s O.K. alarm, and the make-up gun. Busy guy.
Erm, let’s say he’s extraordinarily good at avoiding sexual temptation. Just about any other type of temptation, and he folds like a lawn chair.
He did go on a hunger strike to avoid having the Springfield Isotops moving to Albercurque.
On the other hand, he was unable to resist self-cannibalization when his head was turned into a doughnut.
(Or are we not counting Halloween episodes?)
He’s a hell of a dancer.
He started a successful security business.
He’s good at avoiding death. He has gotten into blunders that could kill most ordinary folks, and has avoided death a number of times (as pointed out in the Grimey episode). Whether it’s a skill, dumb luck, or the fact that he’s an animated TV character, we’ll never know.
