[Bum Catchprase] "You've got your whole life in front of you!"

I live in the Historical District in Galveston. It's a 100+ year-old neghiborhood, and we have alleys behind all of the houses. And it seems that for every couple of blocks, there is a weird person who hangs out in an alley. I'm not sure how they decide which bum/weirdo hangs out where, but they always seem to stay on their 'turf' and not deviate into any other area.

Anyway, I moved a few blocks last week, and found out that I had a new bum. I call him the 'You've got your whole life in front of you!' bum because that's all he says (my old bum didn't say anything, he just drank beer and swatted at imaginary flies- pretty boring). At first I thought he was going to try to panhandle from me, so I was prepaired to shut him down, because that kind of thing gets really old on a daily basis. But he didn't try to get dime one from me, and he seems pretty harmless otherwise, so I softened my stance with him.

After the first few days of him telling me my future, I tried responding to him to try to get a response other than his catchphrase. "Absolutely", "No", and "You do!" didn't work, so I found myself getting more and more complex with responses like "Not on my watch!" and "I like special ice cream!" or even "I pity the fool!". But nothing seems to work with this guy. He's like a wind-up doll that just says the same thing over and over again without batting an eye.

So I'm turning to you guys for a more creative response- What's the wackiest thing you can think to say to someone who says to you, "You've got your whole life in front of you!"? Nothing too dirty, please. I don't want to give him any romantic notions or instigate a garbage flinging tirade.
