How do you say "It's Gon Rain!" in Russian?

This past week i had to say good bye to my assisant. She found another position and i hope her the best, but i will miss her. Fun fact, she's afraid of butterflies. Weird, right?

So this one goes out to her...

I love fun facts. It always great to throw one out when a conversation starts to dwindle. Here are a few:

• The oldest known animal in the world was 'Ming' the 405 year old clam, discovered in 2007.
• If you eat lots of carrots, you'll start to turn orange.
• SCUBA divers cannot pass gas at depths of 33 feet or below.
• Tipping at a restaurant in Iceland is considered an insult.
• Moscow weathermen can be fined for inaccurate weather forecasting!

That last one hits home hard. I had to cancel an outdoor event for work a few weekends back because the forecast was rain, but it ended up being a beautiful day! KHAAAAAN!
