Timely Sonnet

"The future is as present as the past",
the physicist exclaimed, a beer in hand.
"The paradoxes, since you haven't asked,
resolve themselves. I wish you'd understand!".
He said this, then he took another sip,
and looked at me as if I was from Mars.
I'm not, and so I tried to get a grip;
I am no stranger to these kinds of bars.
I play along and hiccup -- "there's no time???
It's really an illusion, all for show?"
"Go back", he said, "kill grandpa, that's a crime.
But he won't be your grandpa, that I know."
That sealed it, so I shot him on the spot.
Turns out he's right and grandma was a slut.
