Instead of sulking about the fact that he’s turning 50 years old tomorrow (January 22), Daniel Johnston is celebrating by setting up a call-in number where fans can leave him “Happy Birthday” messages! Call (936) 463-4688 if you’re so inclined. Johnston will listen to all the messages and most of them will air — along with special musician guest messages — during his 50th birthday radio show special on the new Daniel Johnston Radio on January 22 at 8 PM CT. The live show will also include music and stories from Johnston himself.

You can also support Johnston’s metamucil habit by donating money to Kickstarter, where he is releasing his first-ever comic book, titled Daniel Johnston’s Infinite Comic Book of Musical Greatness. Phew, who says you can’t be productive at 50 years old?
