How about this

You step outside in mid February and realise the scarf and toque you have on make you far overdressed, since the weather is 25 degrees out. You freeze in your steps to contemplate how you could have made a mistake like this, is it the right time of year or did the weather change? Just as you look up you see a sparrow fly by in front of your townhouse, but the weird part is, it drops a copy of the Ontarion at your feet. The last thing you see is the headlines that say "April Fool!" above a picture of a snowman with goggles, flippers, and a snorkel. The look on his face is a little distraught as he peeks out from inside his diving mask, because the charcoal bits that make up his grin are slipping as they melt out of their sockets, giving him a bewildered look, framed by his snorkel dangling uselessly next to his mouth. Right after that you wake up, and you don't know what month it is.
