When life gives you lemons, blow it up. I believe that is the message being conveyed here.
From the site
When life gives you lemons, don’t make lemonade – make life take the lemons back! Get mad! I don’t want your damn lemons! What am I supposed to do with these? Demand to see life’s manager. Make life rue the day it thought it could give Cave Johnson lemons. Do you know who I am? I’m the man who’s gonna burn your house down! With the lemons! I’m going to get my engineers to invent a combustible lemon that burns your house down!
It comes packaged in its own little combustible lemon crate.
The perfect gift for Portal 2 fans, Valve fans, or just plain old lemon lovers, all for the low low price of $19.99. What could be better?
