Portal 2's Cave Johnson rants about citrus fruit in this trailer for an "Electronic Combustible Lemon", which, when ignited, plays an ominous ticking countdown followed by what I presume is the sound of lemons exploding. Sadly, the lemon itself does not explode.
The lemon's case plays the Aperture Science founder's infamous rant from Portal 2, in which he explains to listeners exactly what to do when life gives them lemons.
The bizarre gadget is on sale for $US80 over at e-commerce site Etsy.
