There are so many other options beside ketchup:)

Prank is good though

I'm allergic to ketchup, so that trick would leave me hanging over the toilet

[TulsaGeoff]

I'd say Mustard would work equally well

I would just put a couple drops of visine in the drink if I was really gonna pull a prank and watch them sit on the toilet all night.
