This is embarrassing!
A smart person usually does not have to go around telling people they are smart. It shows in the way they talk, behave, and in their personalities. Idiots, on the other hand, try doing this:
1) Or if you are an idiot thinking you are smart
2) Super-smart person right here
3) A stunning indictment of the educational system
4) You don't say
5) An A-grade dumbass right here
6) Yeah, that's not what Hellenistic means
7) Oh, ok!
8) Your pants are on fire
9) Just slipped it in there
10) The conversation is sparkling
11) Just wow!
12) Sure, sure!
13) Oh, of course, you are!
14) Simply amazing!
15) Great! No one asked.
16) Must be really lonely with the upper floor vacant
