I think the taste of asparagus is worth the inconvenience of whiffy urine.
Incidentally, a colleague of mine went as far as visiting her GP for blood and urine tests, convinced she was dying from a kidney disease. I happened to mention the asparagus thing, she clutched my arm in relief and never looked back.
Bovril and penicillin do it as well.
I get clear pink urine after very very hot curries, it stings like hell as well, but heyho I persevere, the pain is worth it for the pleasure.
