Is there a name for this type of insult: "I am friends with many manly men. And Gary."?

Is there a term or word appropriate to describe the trick of using a general term and then explicitly adding a specific term to strongly imply that the specific is not part of the general? The trick I see never uses a negation or a word like "except." It simply "adds" something at the end as a slight or insult to the thing being added:

My classes are filled with really smart people. And John.

Before you are the best and most clever and most attractive and Susan.

Solution 1:

TV Tropes call it "My Friends And Zoidberg" trope:

http://tvtropes.org/pmwiki/pmwiki.php/Main/MyFriendsAndZoidberg

A standard comedy trope which, at its core, takes the form:

"Group A ... and Bob."

It is often expanded to mention two or more groups:

"Ladies, Gentlemen ... and Bob."

In either version, Bob is already expected to be among the group(s) in question, but is singled out as if he's not, usually at Bob's expense;

This can be Played for Laughs in cases where it's literally impossible for Bob not to be a member of the groups mentioned.

It can also be used to deliver a Stealth Insult: "We welcome members of all professions, and lawyers." Or, inverted, it can even deliver a compliment: "You morons, and Bob."

This may be another example of a paraprosdokian. See this answer.
