A South Perth bottle shop manager has described the bizarre moment a group of Australia Day pranksters rode a bobsled into her store's drive-thru while excitedly chanting "Cool Runnings." 
Footage of the strange stunt, which shows four men pushing the sled across Mill Point Road, has since gone viral online.
Local Liquor Baron manager Natasha Garlbraith told WAtoday the group of about eight men made a short stop at the shop's drive-thru on Tuesday to buy ice.
"I walked out and they were screaming out Cool Runnings," she said.
"They were just wanting bags of ice, they were really cheerful.
"I don't think they were intoxicated, they were just excited about being in a bob-sled."
After the "random event" Ms Garlbraith said the group headed towards the South Perth foreshore, assumedly to join in the Australia Day celebrations.  
"I don't think they could do it any other time of the year except the roads were blocked off and there weren't many cars," she said.
