Make the tag line part of the drawing. If you do that, it should be the drawing of Flaco with his arms above his head and SQUEE! as was on the button.

Hey All!

I've just read through the preceding 5 pages of posts and I've got some thoughts that I thought I'd share.

The tag lines seem to split into different types:

1. too generic

if the tag line could apply to beer or washing powder, then it's probably a bit too general. And dull. Or cliche.

2. in jokes

I've been reading the comic for years so of course the characters are more than familiar, as well as the occasional trips into geekdom.

However, I'm presuming the tagline should be targeting non-readers?

3. wrong impressions

If the tagline only mentions pugs or Vulcans or geeks then I think that it misrepresents our beloved comic.

- So Finally:

I believe that the tagline should, in some neat and concise way, encapsulate what it is that makes Sheldon different - since many comics are essentially an amusing look at the world, are free, are read in the morning etc.

Sheldon's key values are about friendship. It's about your Grandad and your talking duck.

Whilst it *is* about a billionaire kid, the comic doesn't read as childish nor does it have that awful air of excessive money. So I think these aspects shouldn't make the tag line.

Of course, having said all this, I'm just as stumped as everyone else!

Good Luck!

(I'm still working on my taglines - they are still rubbish)

Well, with that being said, how 'bout

Sheldon - It's Different™

LOL

No but seriously, I came up with some more:

"Sheldon - Not Your Grandparents' Webcomic"

"Sheldon - Bringing The Funny Since 2001"

"Sheldon - Funny. Free. But not Funny-free!"

"Sheldon - Read it, or else!"

I'll give it a shot.

-A talcking duck! Tee hee.

-One duck, one lizard,two humans, unlimited fun.

-This ain't your parents funny pages!

-A billionare boy and his talking bird. What the duck!?

-Sheldon: Impending laughs!

Sheldon: It is what it is.

Sheldon: No need for training wheels.

Sheldon: Even Santa wants some.

Sheldon: Look before you leap.

Sheldon: The strip that asks; "What Would a Klingon Do?"

Sheldon: For the boy who could buy anything, the most important thing is family.

Let's see, what can be written about Sheldon that would fully encompass all of what it means? The following post may be the answer.

Sheldon: The Only Way To Find Something Better is to Read it Twice.

I think that is pretty good.

Sheldon: A Squee a Day Keeps Depression at Bay.

If we're voting, I have to cast my ballot for "Sheldon: 100% Awesome Sauce" because a) that was my idea before I saw someone else had already come up with it, b) it's short, sweet and to the point, and c) it perfectly encapsulates the awesomeness that is Sheldon.

I'd also like to take this opportunity to beg for a Flaco shirt design. The recent yogi Flaco panel would be perfect! :-)

Sheldon: You heard right! squee.

Sheldon: If you've been looking for carefree laugh, you found it.

Sheldon: It's like that G rated movie on a lazy sunday afternoon, but good.

Sheldon: Summon your inner cheeseball

(shamelessly cribbed from the September 14, 2007 strip)

Sheldon: True brilliance is analyzing stupidity.

Sheldon: True brilliance is saying "squee".

Sheldon: Even ten-year old geniuses get bored.

Sheldon: Sixty kinds of awesome!

How 'bout these, Dave?

Sheldon - A conversational masterpiece!

Sheldon - The best of 2D virtual realities!

Sheldon - The reason pencils were invented!

Okay, one more (hey, I'm gonna try to get my odds up as high as possible).

Sheldon - Behind the chaos and confusion, hilarity ensues!

Sheldon - More fun than doing spreadsheets!

Sheldon - It's not a name, it's an adjective.

Sheldon - Do the wave!
