5x is a rip, don't waste your money.
BUT, IF: you can find a potent source for 20x, take two or three BONG (yes, water pipe's a must). Hold it, hold it...good.
You may then find yourself scuttling along the ceiling, with all your eight legs- for what seems like 45 minutes- making friends with these fluffy velveteen tits, and friendly latex grubs the size of rugby balls.
About two minutes later, that is by established Gregorian clock time, you'll come back to your usual and expected dimension, and happen to be clutching a 9 iron, and a little purple balloon poodle. The clown that's been pumping these little balloon animals out, is nowhere to be found. You may be slightly confused even.
First impulse will be to savagely mangle the puppy's squishy little skull with your club, but yet another minute later into this newly rediscovered reality, you'll forget all the animosity you once felt for the little pup, and instead hold it tenderly, and dearly, and close to your heart. The two of you can then walk hand-in-balloon paw, step by step, in to the setting sunset.
