What is packed but never stuffed? What comes in but doesn't go out? How much does a bowling ball weigh?

A football stadium, A landing (coming in for a landing), Regulation ten-pin bowling balls must weigh no more than 16 pounds

Am I right?
=D
Lol

No I don't think so... my boyfriend gave me those clues as to what he's getting me for my birthday, he does live out of state right now so the landing part may make sense if he's surprising me with a visit... but the football stadium and bowling ball have me stumped lol

Maybe it has nothing to do with the bowling ball, but the number that is the answer... I got nothing. Lol

Oh I know, he's coming for a visit, going to take you to a football game where he will give you a 16 pound box of chocolates! It's what I'd want for my birthday! Lol.
