Why You Can't Hear a Pterodactyl Go to the Bathroom

[tts.alexius]

Why is it impossible to hear a pterodactyl use the lavatory?

Due to the fact that the letter “P” is silent.

 

[Makomo]

Because the “P” is silent, so a pterodactyl in the bathroom would be totally stealth mode, like a ninja bird, leaving no sound behind except for the faint echoes of ancient dino history.
