Howard Wolowitz

Howard Wolowitz is an Aerospace Engineer at Caltech.  One thing that sets him apart from the other 3 cardinal geeks which the Big Bang Theory Universe revolves around is his lack of a Doctorate; a fact Sheldon points out on a regular basis.  He does however have a master's from MIT.

Howard seems to think of himself as a stud and is almost constantly scamming on or scheming to scam on women.  He does this in a way which is often over the top and creepy, which is, considering this is just a fictional TV show, hilarious.  He still lives with his mother and dresses like a hipster from 1965 London.  Speaking of his wardrobe, I love his collection of belt buckles, it seems nearly every episode he's sporting a new belt buckle; all or nearly all of them have a comic book or scifi or video game theme.  Pretty cool.  (Hell, sometimes I think I watch the show for Howard's Belt Buckles and Sheldon's T-shirts.)

Howard's penchant for outrageous pick up lines seems to have sparked an Internet Meme whereby people take the picture of Howard you see on the left, and add a science-y yet brazen pick-up line of their own.

His celebrity crush appears to be Katee Sackhoff.

(Howard is played by Simon Helberg.)
