Every sign has its own unique sense of humor. Some more than others (as some of you can attest to!). Leo and Gemini tends to govern humor, with these two being the silliest, goofiest of signs, the most light-hearted and the ones who love to laugh most. If you have a personal planet (Sun, Moon, Mercury, Venus, Mars) or Jupiter in either of these signs or the houses they rule (3rd house for Gemini, 5th house for Leo), you can be seen as a more humorous person. Same can be said if you have either of these signs as your Rising or Midheaven.
Sarcasm is a horse of a different color. Sarcasm is decidedly fixed sign: Taurus, Leo, Scorpio, and Aquarius, with Scorpio being the most sarcastic sign. If you have several fixed sign personal planets, Rising, Midheaven, or planets in the succedent houses (2nd, 5th, 8th, 11th), you can have sarcastic humor. Fixed sign humor can also be darker and dirtier. Oddly enough, if you have your Saturn at a critical degree, especially if it's also in a fixed sign or in the 1st house, this can also instill a sarcastic sense of humor.
The fire signs (Aries, Leo, Sagittarius) can prefer more physical comedy, and are the pranksters of the signs. The air signs (Gemini, Libra, Aquarius) can have a more intellectual approach to comedy, and tend to be drier or wittier. The earth signs (Taurus, Virgo, Capricorn) may take a little more time to move to laughter, and Cancer and Pisces can probably be the most misunderstood with their comedy. Pisces can like gross humor too.
For everyone, there's also asteroid Thalia (number 23), one of the Muses, who rules comedy. It's common to see this asteroid prominent in the charts of comedians.
