Rusty

Rusty, also known as Tea, is a side character in the Leonard Cinematic Universe. Rusty is known for his love of exercise, and the use of revolting visual, olfactory, and auditory imagery to describe his love of exercise. A particular example of this is his repeated want to "sweat", which is particularly disgusting in conjunction with this often furry profile picture, which conjures up visual imagery of a sweat-soaked, furry body. This is ultimately to the detriment of all those who converse with him, as these descriptions almost always derail the chat into a state of pure disgust.

Rusty is commonly believed to be a sentient cup of tea, which has caused significant uproar in the biological community. It is unknown how Rusty maintains the temperature of a cup of tea (approximately 50c), hence his endothermic or exothermic properties are a hot debate among biologists.
