a thing in the bag
A fake magical thing that Strong Bad pulls out of a paper bag to impress everyone. Homestar Runner hopes to see it one day and does chores for Strong Bad just to get closer to it.
Strong Bad's thing in the bag is fake, but I believe in it more than I believe in my math teacher.
Homestar Runner would do anything to see that thing in the bag, it’s like the holy grail of bag stuff.
That thing in the bag is Strong Bad’s secret weapon.
