I know a few in Portuguese. Most of them are... well, bad. Dad joke tier.

P: Por que chama-se "umbigo"? R: Porque só tem um. Se tivesse dois, seria "doisbigo".
\ *Q: Why is it called "belly button" (umbigo)? A: Because you only got one (um); if you got two (dois), it would be [non-existent word, roughly "belly buttwo"].*

P: Que palavra com oito letras continua tendo oito depois de tirar quatro? A: "Biscoito".
\ Q: Which eight-letters word still has eight (oito) after you remove four letters? A: "Bisc*oito" (biscuit or cookie, depending on dialect).*

P: Por que o três e o sete não se casam? A: Porque são primos.
\ Q: Why don't the three and the seven marry? A: Because they're cousins / primes (both "primos").

• Toc, toc. Knock knock
• Quem é? Who's it?
• Vinte. Twenty.
• Que vinte? Twenty what?
• Vim te dizer para abrir a porta. I came tell you to open the door.

Note: "vinte" /vĩte/ = twenty; "vim te" /vĩ te/ = "I came" + "you" (object).

they're locally known as "piadinhas do tio do pavê" (layer cake's uncle's jokes). The name is also based on wordplay, albeit it doesn't involve numbers:

• [Someone] Fiz pavê! I made some layer cake!
• [Someone else] É pavê ou para comer? Is it [a layer cake / to see it], or to eat it?

It relies on "pavê" /pa've/ (layer cake) being homophone with "para ver" /paɾa 'veɾ/~/pa've/ (to see), depending on how you pronounce the later.
