I'm looking for sentences that contain a sequence of at least two identically-written words in a row, such as the following: "I like that that car is red."
The challenge is to make as long such a sequence as you can.
There are some restrictions, though:
The sentence must be grammatically correct.
The words in the sequence must not be assigned made-up or extremely uncommon meanings--in the above sentence, I might have done this by claiming that my friends and I call cars "thats", and had three "that"s in a row.
The sentence must not be redundant or cyclic--that is, it cannot have a pattern of "A-refers-to-B-refers-to-A-refers-to-B...", or something similar.
The sentence need not be useful in regular writing or speech, but the more sense it makes, the more interesting it is.
Please include your sentence's "score" (the number of identical words in the sequence), and, if you'd like, an explanation of how it should be understood.
I've come up with one that I think has the longest sequence possible in it, and another that might be used in regular writing, but is still very long. I'll add those once I learn how to use the "spoiler" bars, but for now I'd just like to see what others can come up with. :)
Edit: I'm not looking specifically for sentences that consist only of a single word repeated some number of times, but ones that include some number of consecutive repetitions of a single word.
