143

The bus that stops near my house is the 143
When I look at the time it's 1:43h
When I look at random houses, the house number is 143
When I look at the time of a video it's 1:43
I googled it once and funny enough 143 means I love you!

1+4+3=8;
If we turn it 90° we'll get '∞'.
The threads never end.

143 spelled backwards is hardcore sexual intercourse.
