The relic foreskin of Christ

Right, so let me get this straight. somewhere, someway, somehow, there is a nun or monk who is protecting the foreskin of good old JC? The HTC doesn't really do textual shots very well, so let me reiterate what is says in the fuzzy photo:

"According to Catholic belief, there is somewhere, protected in a secret vault, the relic foreskin of Christ. Since he ascended to heaven, his foreskin is the only mortal part of him that remains."

Seriously. I wonder if they pull it out to whip up miracles: placing the dried up, dusty foreskin on the body of the believer - mouth moving in silent prayer asking for the much anticipated miracle... waiting, watching to see if the blessed foreskin can make their leg grow back/eyes to see/leprosy to be cured/etc.

Pardon me as I giggle.
