At the risk of looking like the joke went over my head, the joke falls short on two fronts:
- Pho isn’t pronounced like “foe”, more like “fu-“ in “fuck”
- The dish looks like ramen, with yellow noodles and bok choy. Pho has white noodles and is served with slices of meat, “meatballs”, and herbs.
At the end of the day, this is a joke and it really isn’t worth getting too worked up over. I find it funny more so at the ridiculous idea of having a soup compartment on a scooter, than with the pun
