My wife likes ketchup so much she slathers it on all kinds of different foods, including those I consider her sacrilegious for slathering ketchup upon- like tacos.
Personally I prefer salsa to ketchup, but I guess we've all got to get our daily dose of tomato blood somehow, and some people have stranger cravings than others.
And just so you know this Maximumble comic confirms the fact that tomatoes love how much we love their blood, so suck that red vegetable vital fluid down by the gallon! Stick a straw straight into a tomato if you have to, and don't worry- they don't feel pain!
