Ah think you :D

The idea that Soarin’ loves pie is probably a given.
 
March 14th is known as “Pie Day”, because when you write that date in numbers, you get: 3/14, which is very close to the number pi: 3.14.

I don’t get the joke can someone tell me but I love the pick though like all of bobs work :)

@Billystorm  

Oh, these aren’t really pies. They were made in a factory.
 
A bomb factory.
 
They’re bombs.

At least she didn’t catch him making love to pies

Beware the ides of March.

@Barhandar  

My school had a small celebration for this.

I’d like to think it also has to do with how our calendars (or calendars in general, for instance see which type of calendar you see more often on Google images) are sectioned by month. When someone gives you a date to mark, you go through the calendar by month first, and then find the day. The calendars that are the type where it’s a new sheet that you peel or tear off for each day are rather uncommon, or I mostly only see them in cartoons (or iCal, now that I check my iPhone).
 
Of course, you still have some anomalies like how we celebrate Independence Day as “4th of July” at least more often than as “July 4th”, and then there’s how the format can change when spoken or written depending on the language, even if you’re in the US, e.g. you’d still refer to today as “catorce de marzo” in Spanish, or 2016.3.14 in Japanese and probably other East Asian languages.
 
Being from the US I never questioned it since it’s not like it doesn’t still work, nor do I really question how everyone else in the world goes about it. Or I compared it to how the first unit in referring the time is the hour, whether you use the AM/PM or 24-hour format, not the minute or the second, except I suppose, in some cases where “half-past” or “quarter to/after” expressions are used. (I guess those date back more toward use of analog clocks, rather than digital ones.)
 
That said, at least according to the last time I looked at Wikipedia, the M/D/Y format is also used in Belize and Canada (though, in the latter’s case so is D/M/Y, with the use of French and English, proximity to the US, and use of British English all probably playing a role there).
 
…And I’d rather be able to pull off date puns like these (and May the 4th be with you) than use another format. It might be because I’m American and therefore ignorant to this, but I hardly see or know of any similar puns with the D/M/Y format that are widely celebrated or joked about, considering how much of the world uses it. It’s more often that I see D/M/Y users complaining about the M/D/Y format when they happen in ours.

Last year was even better, since you could go a few more significant figures:  

@Barhandar  
I always figured it’s because we say “March 14th” and not “the 14th of March” so we format it that way.

@Toyminator900  
Only for the “let’s oppose everything and common sense and put our dates in the month-day-year format” crowd, which is basically USA sitting by itself in a corner.

Equestrian Pie…

But this is special… It’s  
3/14/16

Why would he want to do that, Spitfire? There’s starving kids in Africa, you know.
