Stan is often shown with his hands in his coat pockets as he walks, or when in deep thought.
In the later episodes, Stan also has a habit of pinching the bridge of his (unseen) nose and shutting his eyes tightly when frustrated or exasperated, saying phrases such as "Oh no." A good example of this is in "Manbearpig" where he does this motion when on the phone with Al Gore.
Violation of Firearm Laws/Threatening with a deadly weapon: In Mystery of the Urinal Deuce, Stan held Kyle's head at gunpoint and began to threaten him before revealing that he was the one who defecated in the school urinal simply to avoid missing out on recess, He was eventually punished by Mr. Attempted Murder: Stan has attempted to kill Cartman with a laser gun when Cartman almost destroyed the world with his trapper keeper in Trapper Keeper.
In Spontaneous Combustion he and Kyle tied Cartman to a cross, knowing full well that he would die, in order to give Kyle's dad a resurrection.
This is the same catchphrase Trey Parker used in BASEketball.
If he agrees with someone or is unsure of something, he will often state "sure" or "yeah" in a very dull, unimpressed manner.
Whenever he gets mad, frustrated, or gets dragged into something, he often says "Goddamnit!
", not to be confused with Cartman's catchphrase, "Aw! " Often in school, he'll say "Oooooh....." with a slightly higher pitched tone than his normal voice. " This is evident in "Super Fun Time" and "About Last Night...".Attempted Unlicensed Surgery: In "Cherokee Hair Tampons", when Cartman refused to donate his kidney to a dying Kyle, Stan tries to take it by force by breaking into his house and removing it with a saw, however Cartman outsmarts him by using the "Kidney Blocker 2000" to prevent this.Unlicensed Surgery: In "Jared Has Aides", He, Kyle and Cartman preformed unlicensed liposuction on Butters with a hose in order to get him thinner in hopes of getting money from a weight loss scam.Filing a False Police Report: In "The Wacky Molestation Adventure", he lied to the police about his parents abusing him.Hit and Run: In "Two Days Before the Day After Tomorrow", Stan and Cartman drove a boat into a beaver dam, which resulted in the flooding of Beaverton, and the deaths of 'hundreds of millions', despite the population of the town being only 8,000.Another example is in "With Apologies to Jesse Jackson", when he does it all the way home from the set of Wheel of Fortune.
