Use a tank at the drive-thru (it's unlikely to fit, and the road will probably be ruined too)

Walk into the middle of the store and say "I like trains".

Do this, apparently:

Use the roof as a vantage point to snipe the Westboro Baptist Church protesters with either paint-balls/.30-06 ammo

Walk in with a dead cat under your arm, slam it on the counter and shout "Look, I don't care anymore, either you pay me for these or I stop bringing them!"

Believe it or not I went to the same primary school as those guys.

To get banned, walk out the loo and say 'Why does nobody know how to flush the toilet after they've had a gak!?!'

Walk into the play area and inquire aloud, "Who put clothes on all these children!?"

Walk in, stare into the manager's and say 'I stab people', then smile......wait for a result (it is normally the police)

Order a Big Mac at the counter and say you'll make it yourself, proceed to use a flamethrower to cook the food, accidentally jam the trigger (do flamethrowers have triggers?), proceed to accidentally burn the place down and finally run around the parking lot desperately trying to get the trigger unjammed.

Several simultanious cans of silly string emptied over the counter at everything and everyone should get the job done.

Demand a litter of cola and agrue profusely when told they don't have it.

order a dozen chesse burgers with extra sauce, take the buns off and see how long you can get them to stick to the ceiling.

Sit on top of the soft drink machines and stare down the cashier for as long as possible

Break in at night, then replace all the softdrinks with crude oil.

Arrive at McDonalds either by:

1) Landing drop pod on roof. Proceed to then use your chainsaw to cut a hole into the roof.

Or...

2) Landing drop pod in drive thru. No I don't care if there is a car there. It's the car's fault!

Throw a pie at the cashier's face.

Dress as a preacher, enter and then preach the word of our lord, the colnel to the sinners and heretics of the cult of the clown.

Bonus points for getting a congregation of friends

Pee in the fountain drink machines

Drop a live grenade in the toilet bowl.

Most disturbing...

You need a bunch of friends for this one.
Go in the place one by one and quietly sit down. Don't order food or anything, just sit down.
When the last of your friends has sat down, they have to shout, "Maccies Maccies Maccies!" and then everyone has to run out the door.

Works equally well with Starbucks and Costa, too.

Take in your laptop and play heavy metal repeatedly through the biggest speakers you can get.

Actually feth that, play Cradle of Filth. The old stuff. Uncensored. Whilst screaming along with it.

Hump the Ronald McDonald statue.
For extra hilarity, strap on a chisel / hammer onto your pelvic region, so that you leave a hole after defiling the mascot.

Convince others you are not a werewolf by shouting in their ear "I AM NOT A WEREWOLF"
