in reply to Select randomly from a hash

Hashes require an even amount of elements. The first of each pair is the key and the second is that key's value. So warnings would tell you your %verbs hash contains an odd amount of elements. Take a look at perldata. I think what you are looking for are simple arrays, and getting random combinations of two arrays via rand. Something like this should work:
use strict; use warnings; my @pronouns = qw/He She I Me/; my @verbs = qw /jumped ate laughed cheated/; print $pronouns[rand @pronouns] . ' ' . $verbs[rand @verbs] . $/;
