Honestly, it was unintentional. The commissary had a very limited supply of candles. I didn't want the little kid ones, with Dora or Sponge Bob. I grabbed the first package that looked normal. Except they weren't. They are the kind that relight after you blow them out.
I didn't tell Allen that. Here he is anticipating eating yummy cupcakes.
And his first attempt to blow them out
and realizing what was going on...
and making another attempt
eventually he just spit on his fingers and squeezed them all out.
