I saw one of those lil' tiny european cars and the license plate cleverly, somehow, spelt out "Decepticon". I laughed so hard. Those tiny robots that can turn into tiny cars and they cause destruction. I could just see that car transforming into a decepticon right on the freeway and taking out the cars on the freeway.
Another one that made me laugh was those cars that look like a box, it might've been an actual car named "box". Anyway the back window read "Brave Lil' Toaster!" I giggled.
There was another one that made me laugh but I dont remember it.
