Happy Mother’s Day was trending worldwide this morning, giving some a bit of a panic attack. Forgetting Mother’s Day? Oh, the guilt that would ensue! Forget about “you never call” or “when are you going to give me grandchildren?” Try suffering the wrath of forgetting your mom on her special day!

Confusion abounds.

Turns out, it is Mother’s Day in Spain. And perhaps Mozambique.

Of course, Americans are blamed for the panic.

Don’t blame us, British! Our Mother’s Day is next Sunday. It’s not our fault some countries get the date totally wrong. You should all work from our calendar and save everyone the hassle. While you are at it, start using our measurements instead of that silly metric system deal.

This guy figured out a way to cover his behind no matter what.
