350. Vandalize
351. Counterfeit Money
352. Pay 1 dollar for a 5 dollar item and then somehow get away with it. (Make sure the manager finds out and then refuse to pay for it)
353. Try to get 15 items through the 10 or fewer items lane and then say you only have 10 items because you taped 6 items together, and that counts as one item.

341: Bump into random people. Every time you collide, say "BOING! 10 POINTS!"

355. Make a card tower in the aisles... with shelves as cards.
356. Yell "I love 'Drake and Josh!'" around the aisles, and slap anyone who complains
357. Yell "W = May go into Walmart, U = Use a vehicle, L = Live close: because Catch-22! What law says we have to obey Catch-22? Catch-22! And what law says the government doesn't have to tell us what Catch-22 is? Catch-22! *put tinfoil hat on* The government is watching!"
358. Yell "This Walmart is relocating to 34.2°N, 50.976°W." (Search that up on Google Maps)

346. Walk into Walmart in a left shark costume and tell everyone that "fish are friends, not food"

360. Dress up as the manager and yell "All prices will be rounded up to the nearest 1000 dollars over the intercom."

361. Remake a Primus video. (Youtube them, and you'll understand)
362. Bring in a bunch of squirrels and host a squirrel fishing tournament.

Revive time. This thread gave me a new lease on life.
363: Take the manager hostage with a nerf gun. Then demand all the skittles in the store.
364: Go all out Rambo and shoot as many employees as you can with a paintball gun until you're caught.

365: Steal a bb rifle, * shoot out all of the security cameras, and then try to return it for a refund.
We've come full circle...
*(One of the good ones that shoots the steel bbs and is pumped up manually.) Mine like this'll put a hole in a rat's skull, so this is probably doable... (It is still the original seals from 1986, so it probably doesn't hit as hard as it used to.)

366: throw hot dogs at customers

367: Make a flamethrower with a bottle of charcoal lighter fluid.
