This question gave us a new idea

A certain man put a pair of rabbits, male and female, in a very large
cage. How many pairs of rabbits will be produced in that cage in a
year if every month each pair produces one and only one new pair,
consisting again of a male and a female, which, from the second
month of its existence on, also is productive? It is assumed that none
of the rabbits die in that year.
