His signature logo, a drawing of his head in a crash helmet directly atop a pair of shoes with no visible body, was from an iconic early sketch, "Balloon Ball". The "stunt" consisted of his standing in a hole in the ground reciting "balloon ball" as a which was supposed to imbue him with the ability to not be harmed by anything, as a mobile pile driver rammed the top of his head. When pulled out of the hole, he was as his eventual logo depicted: his helmeted head sitting directly atop his running shoes, the whole of his body supposedly compressed between shoes and neck.
