I will say:

From Wikipedia:
Zeus had the time to tear her out of the womb a premature fetus, squeezed in his hip and successfully carried it. Thus, Dionysus was born by Zeus from a hip. When Zeus was suffering from childbirth, Poseidon served him with tuna.

Who knows what this has to do with tuna?!...

You know, pregnant women - they are so capricious!
