Last Week Tonight host John Oliver appeared on the Late Show with David Letterman and discussed how far he’d go to make people laugh — including injure himself.
The 37-year-old comedian told Letterman that during a USO Tour to Afghanistan in August, 2013, Oliver had just finished performing a set for the troops when a soldier asked if he’d tase himself. Oliver, looking for a laugh, agreed.
The visit marked the first USO tour for Oliver, who was touched by the trip as his wife is a former Army combat medic, who deployed to Iraq.
The next season of Last Week Tonight is slated to return to HBO on Feb. 8.
