Thirty-seven

• On the 9th of January, glEbs suggested to Jick and Skully that "when ever you buy 37 of something, it should say "In a row?!". Soon after, the number of shelves allowed in a Display Case was extended to be thirty-seven. Trying to add more than 37 shelves results in the message "Try not to add any more shelves to your display case on the way through the parking lot!"
• Obtaining thirty-seven of an item at once will result in the message "In a row?!"
