I've come across an issue where cowsay fails with the following unhandled perl error. Changing the argument here even slightly seems to make it work so I imagine this is very unlikely edge case but posting here just in case anyone else gets this same error and is as perplexed as I was...or if someone feels like digging through 5 year old perl :)
