Amanda Bynes Is Crazy, Part 34

Amanda Bynes accidentally drenched her pet Pomeranian with gasoline while building a fire in a residential neighborhood ... then raced to a nearby liquor store to clean the pooch.

At 8:39 PM ... Bynes can be seen bursting into the liquor store and darting straight for a restricted "employees only" area -- while holding the dog in her outstretched arms. 

The cashier -- sensing something was wrong -- rushed out from behind the register and chased after Bynes to see what she was doing. 

TMZ spoke to the owner of the store who tells us ... the cashier detected a strong odor of gasoline and observed Bynes attempting to rinse off the dog in a sink in the back area. 

We're told ... as soon as the cashier confronted Bynes, she "freaked out" and left the store without further incident.

Look, this footage isn't particularly fascinating other than the fact she's carrying a gasoline soaked dog around. Darlin', the Internet will love you so long as you just act crazy, but if you were to accidentally set the little puppy dog on fire when you're acting crazy, they would have been coming after you like an Egyptian mob.
