Id X

The character of X was developed while Y was studying for his master's degree at Oxford University. A sketch featuring the character was performed at the Edinburgh Fringe in the early 1980s. A similar character called Robert Box, played by Y, appeared in the one-off 1979 ITV sitcom Canned Laughter.In 1987, one of X's earliest appearances occurred at the "Just For Laughs" comedy festival in Montreal, Quebec, Canada. When programme co-ordinators were scheduling Y into the festival program, Y insisted that he perform on the French-speaking bill rather than the English-speaking program. Having no French dialogue in his act at all, program co-ordinators could not understand why Y wanted to perform on the French bill. As it turned out, Y's act at the festival was a test platform for the X character and Y wanted to see how the silent character's physical comedy would fare on an international stage with a non-English speaking audience
