I think just about everyone here is here because there biology teachers don't teach them! haha

restriction enzymes are not in our body.

@sarshoy we have dnase enzyme that does cutting but unlike restriction enzyme they do not cut at specific sequences.

@matzecc I agree with you in that the particular restriciton enzyme she mentioned, EcoRI, is found in E. coli, a bacterium. But it seems unlikely that higher organisms such as humans wouldn't have restriction enzymes (or equivalents) also. We too, like bacteria, in certain situations have to cut our DNA (e.g. during crossover events in meiosis).
