Punctuation too:

“A panda walks into a cafe. He orders a sandwich, eats it, then draws a gun and fires two shots in the air.

"Why?" asks the confused waiter, as the panda makes towards the exit. The panda produces a badly punctuated wildlife annual and tosses it over his shoulder.

"I'm a panda," he says, at the door. "Look it up."

The waiter turns to the relevant entry and, sure enough, finds an explanation.

Panda. Large black-and-white bear-like mammal, native to China. Eats, shoots and leaves.”

― Lynne Truss, Eats, Shoots & Leaves: The Zero Tolerance Approach to Punctuation

You see a panda walk into a bar, duck down on the floor and get to the nearest exit. They be cray cray.

"Can I go to the bathroom?"

"I don't know, can you?"

"Yes, I physically can, but if you don't give me permission, I CANNOT use the bathroom without repercussions."

Fuck, the memories that this brings back have triggered me, lol.

Sighs "May I come in?" "Yes- no wait!" Involuntary blood donation

Alternate ending: In life the vampire had been a logician, and thus intepreted the statement as an implied "yes"...

Sigh. "No, I can't."

In Spanish, may and can are the same verb: poder. Asking ¿Puedo ir al baño? can mean both may I go as well as can I go. And if you wanted to be somewhat eloquent, it can also mean am I able to go
