MONKEYS just want to have fun - and brandish dangerous weapons.

At least that's what a group of bar patrons in Patos, Brazil, learned earlier this month, when a capuchin monkey ambled inside and proceeded to sample leftover rum on the tables, UPI and the Brazilian news website aRede reported.

After the long-tailed creature had guzzled its fill, it somehow came into possession of a kitchen knife almost as long as its body. With the powerful weapon in hand, it began chasing the men in the establishment; according to local fire Lt. Col. Saul Laurentino, it left the women alone.

"It was a bar staff oversight that ended with the monkey drinking some rum and taking the knife," Laurentino told aRede.
