and of course, un-ordered lists. 
In no particular order:
when something makes me laugh so hard and for so long that I’m gasping for breath, my abs are cramping, and my scalp hurts. It’s like a different kind of orgasm.
a fly-by of fighter jets. Football game, fourth of July, airshow, whatever.
after a professional football game, when many of the players on opposing teams take the time to seek each other out for a handshake. It’s not the mandatory line-up/slog performed by junior-high kids after an amateur-grade match - these guys, on their own initiative, are going out of their way to pay their respects to each other after a brutal contest. It makes me feel good, gives me hope for civilization.
the feeling I get when grilling out in the evening. A nicely shaded deck in the backyard, spiced chicken ribs on the grill, applewood chips smoldering away underneath, I’m into my second beer, and the scent from the grill wafts up…that’s a moment of pure happy.
harking back to Maggie’s #3: if I want to be happy while driving, I pull up Prince’s “Kiss” on the iPod and turn the volume up to 11.
shared cultural references. When you spit one out, and at least one person within earshot understands its origin and significance. Contemplate this on the Tree of Woe.
spring, when you can finally go outside and be comfortable again in t-shirt, shorts, and sandals.
new snow. yeah, I’ll have to shovel the driveway again, but the dirty, crusty winter world looks so much better when it’s blanketed in virgin-white snow.
watching border collies do their herding thing. They are smart and passionate dogs, extremely energetic, excited about doing what they do, and it’s a pleasure watching them cooperate hand-in-glove with their handlers.
the smell of sage in the desert southwest. It smells different after rain than it does when bone-dry, but both are intoxicating to me. I don’t know how much of that effect is because of links with old memories of family vacations, and how much is because it’s just a damn good smell, but there ya go.
For some reason I feel like making this before I read the other responses in this thread. Here goes:
(1) Driving in my Jeep with the doors off or top down when the weather is nice
(2) A happy hour or party when I like the company I’m in
(3) Playing with little kids
(4) Playing with my dog
(5) When my husband does cute things to make me laugh
(6) Inside jokes
(7) Riding on a jet ski (not a frequent occurrence, but it does make me happy)
(8) When a friend of mine sees something related to weight training/bodybuilding and tells me they thought of me
(9) When my makeup turns out the way I wanted it to look
(10) When I get together in person with a good friend that I haven’t seen in a while, and there’s those initial moments where we have so much we want to tell each other that we both get out of breath
Also want to mention that there are some solitary activities that I really like doing, like reading and writing and organizing stuff. But I feel like those activities are more soothing. They’re pleasant and they calm me down, but I think of happiness as a more energizing feeling.

Great idea for a thread.
Your #5 is one of my favorite things! It’s such a great feeling.
This thread made my day! I thought I had 10 things to list but as I read everyone’s posts I found more and more things that I would have to add to my list! I guess what I’m saying is, that even though some days are pretty crappy we all have a lot of happy things in our lives.
Thinking about how young the universe is and how eventually even a trillion years will be a rounding error.
Meaningful time with nieces and nephews.
A good stand up comedy special. Doug Stanhope, Louis CK, Bill burr, George Carlin, Patton Oswalt, etc.
Going hiking and reminiscing in my old college town.
A cold shower after working outside in summer.
Fireball whiskey or old crow and a good movie after work.
Fall is coming up. That means nice weather, beautiful scenery, vacations from work and back to back holidays (Halloween, Thanksgiving and Christmas).
I have millions of songs, movies and TV shows at my fingertips anytime I want them.
Memories of all the good times I’ve spent with good people. Too many to isolate just one.
Having so much food to pick from. All the meals I’ve eaten, restaurants I’ve been to, dishes I’ve tried. And I’ve barely scratched the surface. Yet another benefit of living in a large city, all the food.
(because fuck it, my list goes to 11). Campfires.
