[[A person is holding a cup at arm's length.  Waves of stink are rising from it.]]
Person 1: Oh God, how old is this yogurt in your fridge?
[[Someone speaks from off-panel.]]
Person 2: What's hte expiration date?

[[The first person holds up the cup to look at the bottom.]]
Person 1: May 12th, but there's no year.
[[From off-panel again.]]
It's May 7th.  So it's fine.

[[Now the second person is on panel, and the first speaks from off-panel.  The second person is sitting down working on a laptop.]]
Person 1:I'm not sure.  When it was packaged, was civilization using the Gregorian or Julian calendar?
Person 2: Okay, I'll throw it out.
Person 1: No, it might still be good!

{{Title text: I am firmly of the opinion that if something doesn't have a year on it, every time the expiration date rolls around it is good again for the two weeks preceeding that date.}}
