When Happy and the Doc return the Bicker Clicker to the psychiatrist, the psychiatrist is happy that it is at 32 (a new record). The couple tell him that it went past 99 and is 131 (twice). That is incorrect. Since both the unit and tens place must have a 0 to count single digits and multiple of tens, the clicker would go from 99 to 00. Thus, the count is actually 132. A very serious mistake for geniuses and not for writers.
Cabe states that sloths mate for life.
That's not so. They are known to have different mating partners.
