That last ret wasnt in his code.. but even with it it would not be
endless..
that last ret will never be executed. he will ret three times on the
same ret back to the respective returnspots,
and then the fourth time it would end the program...
like this:
calls second -> calls third ->ret to after call third -> rets to after
call second -> calls third -> rets to after call third -> ret and end
program.
everytime on the same ret..
