Drowsy toddler loses the plot after being given medicine before surgery

Amusing footage of a drowsy toddler giggling after being given some medicine before going into surgery.

The video, shot in St Louis, Missouri, USA on Tuesday, shows the two-and-a-half year old boy behaving in a comical way before he went to have hernia repair surgery at Mercy Hospital.

"His mom, dad and grandma were all entertained by his giggles and goofiness," the filmer later wrote online.
