A but tuba

It started way back in history...that I became a palindrome lover.
When I was introduced to them in math class I thought they were the coolest thing ever.
A number that was the same frontwards and backwards.
Simply 123454321.

Later on, I realized there were words and phrases that were also palindromes.
racecar
No melons no lemon
Lisa Bonet ate no basil.
Go hang a salami, I'm a lasagna hog.
Madam I'm Adam
A Toyota's a Toyota
and more.
I am not necessarily obsessed, but I do make a clicking sound with my mouth whenever my odometer reads as a palindrome.
