I can do 16 !
A student asked his english treacher how many times could you write and consecutively in the same sentence and still be grammatically correct. The Teacher answered 5 and told the class about a sign writer was repainting a new sign outside the Rose and Crown. The landlord came out and asked him to leave a bit more space between the Rose and and and and and Crown.
A student asked the teacher if there should be any commas between and and and and and and and and and?
The teacher replied, using punctuation it would more correct to ask if there were any commas between the and and and, and and and, and and and, and and and and and and and! - which gives 16 !!
You could ask if any of these ands should be in quotes? but I'm stopping now!
