Knuth can store all integers between 0 and 127 in 4 bits.

Knuth's brain is the most powerful source of energy known to man. Unfortunately, harnessing it would destroy mankind.
Knuth recently created a new sorting algorithm. Its performance is O(1).
Knuth invented literate programming so that TeX could be compiled by less capable compilers. Knuth's own compiler compiles the English.
