"Jackass" star Bam Margera had an emergency hernia operation after injuring himself during a kayaking stunt in Oregon earlier this week.
The prankster attempted a daring 100-foot drop in a kayak with professional sportsman Steve Fisher on Thursday, but the fall did not go as planned.
Margera posted a photo of himself in a tandem kayak with Fisher on Twitter, and followed it up hours later with another shot of him in a hospital bed, alongside the caption, "Hernia operation after 100ft kayak drop." He was still in the hospital on Friday.
Over the years the TV jokester has been hospitalized numerous times following outrageous stunts. Last summer he was hospitalized with broken bones after falling down a flight of stairs while "horsing around."
