It's once again time for the Fill in the Bubble Frenzy with boy genius Mal and his talking dog Chad! Tell us what goes in the speech bubble and win any T-shirt available in the NeatoShop -take a look around, pick one out and tell us what shirt you’d like with your submission in the comments. If you don't specify a t-shirt with your entry, you forfeit the prize. Enter as many times as you like (text only, please), but leave only one entry per comment. For inspiration, check out Mal and Chad’s comic strip adventures by Stephen McCranie at malandchad.com. Good luck!
Update: The winning line is from Matt, with the entry That's the last time I try the "Knock knock. Who's there? Bananna." joke! Matt, however, did not select a t-shirt.
