It’s more “which came first, the chicken or the chicken egg”. It’s a useful phrase to describe a situation where two things necessarily depend on each other. Chickens must come from chicken eggs, and chicken eggs must come from chickens, and one had to precede the other.
(In the actual case of chickens, it can be resolved easily - by defining “chicken egg” as either an egg laid by a chicken or an egg which contains a chicken, you will obviously and quickly draw a conclusion.)
Destructoid was so good for so long. Between this and the fact that they started to bug me about my ad blocker, it’s time for me to stop giving them views.
