(second), (third), etc. in common lisp

so if I want to express the third element of some list I can write
(third '(a b c))
This works all the way up to (tenth).

WTF? Why would they include built in functions like this? Seems insane coming from C and Java

I was talking about:

((if foo + -) 42 13)
Will either be 55 or 29 depending on the value of foo. As for the order of evaluation, I'm pretty sure functors first then arguments.
