My Father Has ESP

Barely three days after I sent my parents this postcard, what do I get in return, but this?

(Not the copy I got, but you get the idea of the content from the picture)

"Tim," reads the note on the cover, "I thought you might enjoy this wafty magazine. Dad."

Thanks, Dad. Thanks a bunch. Honestly, the old bastard is cleverer than he seems - even to himself.
