What's Wrong With This St Patrick's Ad?

HOW COULD THEY!? This well-meaning poster in Canada is supposed to spreading the joy of St Patrick's Day (and promoting Guinness), but it's raising a few eyebrows instead. 

The 'preferred foliage' ad is a good idea, the problem being that they've used the wrong foliage to represent Ireland's favourite day.

Yeah, the 4-leaf clover ain't no shamrock. It's a four-leafed clover. Which apparently is no good.

We'll be honest, this would've totally flown under our radar, but it probably should've been picked up by SOMEONE at Guinness HQ. What with them being an Irish beer and all.

I thought if anyone would be able to get a shamrock right it would be @guinnesscanada. I guess not pic.twitter.com/7B0CeF4bqi

It can't be easy with all that Guinness flowing through your veins, creating double vision/extra shamrock leaves - there's always next year team!
