undertalesans2231: Hey sans may I ask...how many ketchup bottles can you drink until you get tipsy?
-----------------------------

ketchup doesn't actually have much of an effect on me, which is why grillby didn't think it was much of a big deal for me to have some when i was younger.

now though, i tend to drink a lot more then i should... so uh... i kinda get a buzz from it...

to answer your question though, let's just say it takes a lot of em'.
