Yes, that's the stuff that turns your urine yellow. Speak from experience. Unfortunately it also brings me out in an itchy red rash so I don't take ant penicillin based drugs now. Richard will be ok as long as nobody even offers him a pint, so don't. Trevor has some replacement heads that are nameless, but thry look like Grovers. He's going to put one on later, and see if it works, otherwise we'll try your Schallers Richard, thanks. See you sll tomorrow, weather's going to be ace.
