Even if they don't, you could still have the DUmmieFUnnies.com domain read files and folders from your blogspot site. Not a very good solution, I know, but doable.
I used to have a free website for my band using 'Dreamwater.com', which, as you pointed out, is very long and made it tough to put on a business card.
I purchased a website name that cost me $8.50 a year which allowed me to 'point' to Dreamwater. Anyone looking up the band name (Ransom BTW) only had to put www.ransom.com or just 'ransom.com' to be taken to the DreamWater website.
Worked real well, until I discontinued the site.
