There’s a new mug out from Etsy creator, HX5 Designs that brings Doctor Who and the Big Bang Theory together in the best possible way. The adorably illustrated mug features a Dalek inspired version of the Sheldon’s favorite bedtime song, Soft Kitty.

“Soft Dalek
Warm Dalek
Little Ball of Hate
Happy Dalek
Sleepy Dalek
