Why does certain assembly code doesn't have pop ebp in function epilogue?

Those familiar with x86 assembly programming are very used to the typical function prologue / epilogue:

push ebp
mov  esp, ebp
sub  esp, [size of local variables]
...
mov  esp, ebp
pop  ebp
ret

Why does this assembly code doesn't have pop ebp in function epilogue?
