I have a weakness for multilingual puns. Here are some:

• Why are Tamilians punctual? Because, for them, time is 'mani'! ('mani' is Tamil for time)

• What is valet parking? Parking 'valai'! ('valai' is Tamil for work).

• A trilingual pun: How do you address your pal? Hey 'doodh'! ('pal' is the Tamil word for milk, as is 'doodh', in Hindi).

These aren't mine, but still nice:

• What word can you make with four 't's and one 'g'? Originality.

• What book can hold a bicycle? Encyclopedia.
