Need help with query with "where in" statment

[Kenneth Yeung]

I have a list of user ids that I need information from a table.

I've been using
SELECT * FROM users where users.id in (141,139,140)

I just want to know if there is a way to get MySQL to return the results in the order I give it in the set.

I need results in the form of 141 then 139 then 140

id | first_name | last_name
------------------------------------------------
141 |
139 |
140 |

instead of

id | first_name | last_name
------------------------------------------------
139 |
140 |
141 |

Any help will be much appreciated
