"Not the sharpest tool in the shed, that's for sure!" one viewer commented.

Deputies are still looking for the suspect, who is 5 feet, 8 inches to 6 feet tall, according to the post. He was dressed in a black hoodie, pants and shoes with "neon yellow gloves," officials said.
Investigators also suspect that a driver in "a light-colored four-door Dodge SUV, possibly a Caliber," dropped off the man before the robbery, according to the Sheriff's Office.
"The same vehicle may have waited down the road and picked up the robber after the crime," the post said.
The suspect also might have attempted to rob another bank earlier that morning, but the building's doors were locked, deputies said.
If you have any information about the suspect or the robbery, call the Sheriff's Office at 318-675-2170 or Crime Stoppers at 318-673-7373.
