In case you forgot that Vin Diesel was a big geek, he shamelessly reminded you on his Facebook page July 19.

The big man was celebrating his 48th birthday in his own style with this gorgeous cake shaped like Dungeons & Dragons books.

Diesel has long been open about his fandom with the table top role playing game and about how it helped him shape his identity and build confidence

He also said as much to Jimmy Fallon on The Tonight Show.

Get through the parenting anecdotes to hear him talk about the internet rage. The first comment I read about his casting was a lot worse than, "Noooooo".

Yup, Harry Potter can rap. The good part starts a little after 2 minutes in the video.

In a surprise move, further distancing himself from his boy wizard persona, Daniel Radcliffe, skillfully performed Blackalicious' "Alphabet Aerobics" on The Tonight Show Tuesday night.

Radcliffe says he was initially really into learning Eminem lyrics, and calls his fascination with memorizing fast paced rap songs "a disease."

But what does Ron Weasley think?

For the third time, Simon Pegg flexes his nerd muscles to appear on The Tonight Show as a sloppy drunk Ron Weasley.

The schtick is the same as it ever was: poor Ron Weasley has turned to drink after the world only cares about the exploits of the Boy Who Lived.

His heart's at least in the right place as he shows up on late night to wish his best friends a happy 35th birthday.

Things even have taken a turn for the worse as it appears Hermione left the penniless ginger (again) for someone, probably a Slytherin, else.

Jimmy Fallon tries to both cheer up the soused wizard and protect his talk show audience from Weasley's desire to show his junk.

Humor ensues.

The last time Drunk Ron Weasley appeared on The Tonight Show, it went just about as well.
