Quicksand Fans

I happen to be thumbing through a new edition of The Guiness Book of World Record and thought this would make a good entry.
Has anyone ever noticed a entry for quicksand? What do you think would make a good entry(s)? Like what's the longest someone has been in quicksand before being rescued? What other kind of entries can we come up with here.

How many times an actress has been filmed in Quicksand. Brinke probably takes the cake on that one. With Stefani or Paris coming close behind?

I heard one instance where it took a gal an hour to sink to her chest believe it or not and another two hours for her friend to get her out.
Another case on the BBC heard a instance where two gals were stuck in it for an hour along a popular stretch of beach before anyone noticed them waistdeep in it and took another hour to rescue them.
Another entry could be the MOST in quicksand at once.
