Jdeveloper Tip of the Day

Today when I launched my local Jdeveloper (Technical Preview 4) I read the Tip of the day (I hardly do that but still don't want to stop it permanently by unchecking so at startup checkbox) and here is the tip:

"
Microwave Safety

Aluminum foil pierced by a fork on a bed of ball bearings is not microwave safe."

Isn't it funny? What this tip is doing in Jdev?
