I Can Lick 30 Tigers Today! and Other Stories is a children's story book written by Dr. Seuss and first published in 1969. The title story concerns The Cat in the Hat's son, who brags that he can fight 30 tigers and win. He makes excuse after excuse, finally disqualifying all the tigers until he must fight no tigers at all. The illustrations are notable for their use of gouache and brush strokes rather than the usual pen and ink. Others stories include "King Looie Katz", another warning against hierarchical society advocating self-reliance, and "The Glunk That Got Thunk" about the power of run-away imagination. Illustrations for "The Glunk That Got Thunk" make great use of wavy line crosshatching.
