A while back I wrote this useless site where you put in a string and it gives you a Ruby one liner to output that string.

https://monkeynumber.xyz/

i.e. "bird" gives you

ruby -e "srand(267343);puts 4.times.map{rand(97..123).chr}.join"

which will return "bird" if you run it from your command line

I do a brute force attempt at it, but (maybe one day) will peel back Mersenne Twister and get a more optimized implementation.
