A lemon shark is a real thing! It looks like this! Do you think it's called a lemon shark because it prefers lemons to human limbs or because it is particularly sour? Wikipedia says...wamp, wamp. Neither. It's just yellowish in color. Like a jaundiced baby. OK, new question. Lemon shark or jaundiced baby: which is uglier? Also, here's a lemon shark cleverly wordplayed into a lemon shark juicer.
The juicer is porcelain and dishwasher-safe. Its toothy shark protrusion is at your service to turn lemons' guts to pulp and extract every last bit of citrus refreshment from their insides.
