Finally a like-minded individual! This is my memory device for learning about PL: ‘Yo momma is an undeciable regular grammar’.

A more ‘applicable’ joke: ‘Your sister is flexible in bed’.

PL is also applicable to CFGs so you can make a joke like: ‘Your mom got fucked by a herd of yaks’.

ANTLR has a very unfunny name, but the amount of jokes one could make with PEG is infinite. Hell D has a parser generator called ‘Pegged’.
