I work in a box office, and while people generally call with their orders already in mind, one woman a few months back called looking for ten tickets to "Pipey." Pronounced PIPE-y. While we were, at that time, approaching our summer childrens theatre season and I could understand someone looking for "Pippi Longstockings," this woman absolutely insisted that she wanted to take her children to see "Pipey," and that it was some sort of a sequel to "Pippi Longstockings."
After a few minutes of (calmly) trying to convince this lady that she was looking for tickets to a show that didn't exist, I remembered that the high school just down the street had put up a huge sign for... "Pippin," their spring musical. Not one to be proved wrong, however, the woman huffily hung up, saying that she would find out where "Pipey" was playing and would buy tickets there instead.
Oy.
