Those in the northern hemisphere, where you are currently having a cold snap, may appreciate this one (in Australia we are currently having 40-49 degrees Celsius (104 - 120 F), so we may not!)
Wife texts husband on a cold winter's morning: "Windows frozen, won't open."
Husband texts back: "Gently pour some lukewarm water over it."
Wife texts back 5 minutes later: "Computer really messed up now."
Motto? Texting is dangerous!
