Gawain's Word is a segment in Between the Lions.
A Wayne's World spoof featuring two jousting knights charging at each other, each touting a speech balloon with half of a word which was their respective names, then demonstrating the word. The host of the segment is the eponymous Gawain.
For example, one skit featured "Sir sh" and "Sir ark". When Sir sh collided into Sir srk, their speech balloons melded together to form the word "shark." Then they demonstrated the word by running away from a shark.
