When life gives you lemons...

[Voltage]

When life gives you lemons, dress up as life and give the lemons to someone else.

1. Ask for a refund.
2. Chuck them at people.
3. Use it to reveal hidden messages. (Not sure if it works with lemon juice? I think it's grape juice )
4. Make orange juice and leave the world wondering how you did it.

It is lemon juice. U hold it over a flame and it will show up.

Regift them to a friend.

"Don't make lemonade. Make life take the lemons back. Get mad. I don't want your *diddly-darn* 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 gonna get my engineers to invent a combustible lemon that burns your house down."

When life gives you lemons, find someone with a papercut.

Or, just keep them. Hey, free lemons.

When life gives you lemons, you sell those lemons and invest that money in the stock market.

When life gives you lemons, regift.

Hand the lemons back saying "Oh, I don't like lemonade, it makes me think I'm about to have a colonoscopy".

Put them in a compost pile and go back to studying for green gen.

Start having a conversation with them, I mean, they look like nice lemons. Although, if you talk to them nicely today, tomorrow they'll want to borrow your lawnmower, and then the day after that they'll want to borrow your tinfoil hat, and then who knows what they'll ask you for next.

Take the lemons and go down to Pawn Stars. Talk to Rick, "Hey Rick, what do you think these are worth?"

Make beef stew (please tell me someone gets the reference).
