Unemployed Philosophers 3349 Bat-Signal Mug

Unemployed Philosophers 3349 Bat-Signal Mug
When the mug is cold, the Bat-signal lights up the sky - looks like there's trouble in Gotham City!
When the mug is hot, the Caped Crusader appears to save the day!
Microwave safe. Holds 16 oz.
Of course, sometimes the Bat-signal only means the Commissioner has just put the kettle on..
