Yeah, they could lob shells from boxes of Barilla pasta back and forth. Now THAT is the way to fight a war.

You have to be very careful with the 30mm manicotti rounds, i hear. The lasagna rounds just kind of go flat, though.

Funny, I just bought some Ronzoni Manicotti, I'm not sure it was 30 mm., though, only because it was on sale.
The joke of course is that "shells" is a common pasta variety.
