1. JL421 Badonkadonk Land Crusier/Tank

From a 2-star review:

I rev’ed up the engine and floored it! As I got closer and closer, I could see ol’ ‘tardy Tubbs’ face paint a life-size portrait of confusion on a tattered canvas of fear and surprise.

2. UFO-01 Detector

From a 1-star review:

Only later did I see the disclaimer: “For best results, hold directly under saucer.”

3. All reviews by Billy Bob McRobert. An excerpt:

… but I digest … I’m sposed to be talkin about the Xtend-o-Truck. Now that we have this Xtend-o-Truck, the person on the back is always lined up straight! So, when we hit the speed bump he (or she if the girls aint too warn down from the mornin sickness) always flies just one direction: straight toward the truck. We learned pretty fast that you need to do a little hop right before the truck stops though. Otherwise you just wrap your bodily middle sections around the crossbar of the Xtend-o-Truck and it takes a day or two to walk upright and propper again. If you time it just right you can use the bar to sprang up in the air and do some amazin flips and poses before hittin the truck! I even got a few new dents in the HOOD of my truck from Lucas sprangin off the crossbar just right!

While the above list is anything but complete, I hope to see some more contributions in the comments.
