Originally based on a popular series of web Flash animations, The Amazing Adrenalini Brothers (Xan, Adi and Enk), are 'travelling showmen hailing from the mysterious land of Réndøosîa (who) tour around the world staging ridiculously hazardous stunts' (Wikipedia).

'The Adrenalinis are on a mission to amaze people the world over with their mind-boggling feats, which never quite go as planned' (animationmagazine.net). Though the Adrenalini's seem unable to speak in comprehensible English, they can nevertheless understand it. Hence there is a lot of slapstick and visual/physical humour in their shows, though this is more clever and sophsticated than you might expect. Their adventures are generally filled with action, stunts, sight-gags, more premise than plot, and even less commonsense. (me)
