Re: The One-Upper
I think that the things that bother me about the design the most are two-fold.
First, as some one else pointed out, it would be funnier if the green shroom was saying "Oh yeah? Well I saved his life."
Second, and I've had this complaint before, occasionally Ramyb doesn't do a complete finish of the mouths on his characters, like there is on the one up mushroom here. Now, I don't think that it is "slipshod" I think that it's a style choice. I know that for many this makes it seem incomplete, but I think that he (Ramyb) does it because he, as the designer, prefers the way that they look.
I think that there are some people who also don't mind it, or think that in a subtle way it adds a cute factor. Personally, I don't like the choice here, as it just is distracting from the intended pun.
Lastly, and I'm really surprised that no one has mentioned this yet, but this shirt is a little too close to a bewb/boob shirt. I don't think that it is intentional, just that the placement of the mushrooms might be a bit awkward for women of the female persuasion.
